Electronic Circuits can be classified in the following types: Digital, Analog, Mixed-Signal, RFIC and Power Supply. The following table gives you the summary of the characteristics of each distinct circuit type and their applications.
A digital circuit is a circuit where the signal must be one of two discrete levels. Each level is interpreted as one of two different states (for example, on/off, 0/1, true/false). Digital circuits use transistors to create logic gates in order to perform Boolean logic. This logic is the foundation of digital electronics and computer processing.
Circuitsify has experience in architectural analysis, front-end RTL development (Verilog and VHDL), digital verification, synthesis, FPGA prototyping, timing analysis, layout (custom or auto place and route), and back-end foundry design flow support.
An analog circuit is a circuit with a continuous, variable signal (that is, an analog signal), as opposed to a digital circuit where a signal must be one of two discrete levels. Analog circuits within electrical equipment can convey information through changes in the current, voltage, or frequency .Most of the fundamental electronic components – resistors, capacitors, inductors, diodes, transistors, and operational amplifiers – are all inherently analog. Circuits built with a combination of solely these components are usually analog.
Circuitsify has experience designing a variety of products that incorporate complex analog circuits. Analog circuit design usually covers a very broad range of functions which address the amplitude, frequency, or phase of the signals, and there are many generic functions that are needed in system design. Circuitsify has experience designing a variety of products that incorporate these functions into complex analog circuits
A mixed-signal integrated circuit is any integrated circuit that has both analog circuits and digital circuits on a single semiconductor die. Mixed-signal ICs are chips that contain both digital and analog circuits on the same chip and often are used to convert analog signals to digital signals so that digital devices can process them. For instance, mixed-signal ICs are essential components for FM tuners in digital products such as MP3 or radio, which has digital amplifiers.
Circuitsify is one of the industry leading experts in mixed signal design. Particularly in the areas of ultra-low-power design, power management, and device miniaturization for medical and portable applications, we can provide you with the mixed signal design capabilities built on decades of experience and expertise in a wide array of uses and solutions. We’ll help you design mixed signal circuits around power and size constraints, and even help you mitigate risks and position your product for success.
RFIC is an abbreviation of Radio Frequency Integrated Circuit. Applications for RFICs include radar and communications, although the term RFIC might be applied to any electrical integrated circuit operating in a frequency range suitable for wireless transmission. Radio-frequency ICs (RFICs) are widely used in mobile phones and wireless devices. RFICs are analog circuits that usually run in the frequency range of 3 kHz to 2.4 GHz (3,000 hertz to 2.4 billion hertz), circuits that would work at about 1 THz (1 trillion hertz) being in development.
Circuitsify offers an RF circuit design team with passion and experience in these and other wireless areas. We can take your rough concepts to a final product, we can engage with your team on the wireless portions of a project, or consult on a particular aspect of the RF circuit or antenna.With hundreds of projects that operate anywhere in the frequency range from 1 MHz to 100 GHz, we have extensive experience in most communication protocol such as ZigBee, Bluetooth, Cellular protocol including GSM, GPRS, HSPA and CDMA, IEEE 802.11a/b/g/n and more.
A power supply circuit is the circuit of an electrical device that supplies electric power to an electrical load. The primary function of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters. Power supplies can be broadly divided into linear and switching types. Linear power converters process the input power directly, with all active power conversion components operating in their linear operating regions. In switching power converters, the input power is converted to AC or to DC pulses before processing, by components that operate predominantly in non-linear modes
Circuitsify has extensive experience in power supply development ranging from off-line switches, DC-DC converters and battery chargers through linear applications. Circuitsify also has experience with the latest wireless power technology and is now able to integrate that technology into new product developments. Our designs focus on reliability with thorough analysis and simulation of critical aspects such as stability, dynamic impedance, transient response, efficiency and conducted emissions. Custom magnetics are optimized for leakage inductance, core losses, emissions and cost. Our strengths include low noise, high efficiency, transient tolerant and high reliability designs.
A typical life cycle of circuit designs is involved mainly with verification, validation and testing. The verification process is in which a design is tested against a given design specification before tape-out. Validation is a process in which the manufactured design (chip) is tested for all functional correctness in a lab setup. Testing (Manufacturing/Production test) involves screening manufactured chips for faults or random defects, reliability, functional defects and electrical characterization before volume shipment. You may find the overview of the process of the life cycle of a circuit design below.
The main design methodology for circuit, especially for integrated circuit(IC), in today’s electronic marketplace is application-specific integrated circuit (ASIC), System-on-Chip (SoC) and field-programmable gate arrays (FPGA).
