An analog CMOS peak detect and hold (PDH) circuit, which combines high speed and accuracy, rail-to-rail sensing and driving, low power, and buffering is presented. It is based on a configuration that cancels the major error sources of the classical CMOS PDH, including offset and common mode gain, by re-using the same amplifier for tracking, peak sensing, and output buffering. By virtue of its h...

A low power consumption AMF (Analog Matched Filter) is proposed which utilizes capacitor Multiply and capacitor Accumulation operations. High speed high precision A/D converter is unnecessary because the proposed circuit directly samples received analog signal. The code shifting MF structure is used to prevent error from accumulating. A 15-tap AMF circuit was fabricated using CMOS process. Powe...

This paper proposes a neuromorphic analog CMOS controller for interlimb coordination in quadruped locomotion. Animal locomotion, such as walking, running, swimming, and flying, is based on periodic rhythmic movements. These rhythmic movements are driven by the biological neural network, called the central pattern generator (CPG). In recent years, many researchers have applied CPG to locomotion ...

Analog and mixed signal design has always been very interesting and when it comes to the design of high-speed CMOS and SiGe BiCMOS optical transceivers it becomes even more challenging. Special care has to be taken while doing the layout of such a circuit that operates at a frequency of 1 Gbps or higher. The focus of our first work was to layout an optical driver and receiver stage capable of h...

Real-time analog multiplication of two signals is one of the most important operations in analog signal processing. The multiplier is used not only as a computational building block but also as a programming element in systems such as filters, neural networks, and as mixers and modulators in a communication system. Although high performance bipolar junction transistor multipliers have been avai...

Current mirror (CM) is the basic building block in analog and mixed mode circuit design. For high performance analog circuit applications, the current transfer ratio, output impedance and output swing are the most important parameters to determine the performance of the current mirror. CM’s are important for analog integrated circuits because of their wide use as constant sources or active load...
