A fully differential Miller op-amp with a composite input stage using resistive local common-mode feedback and regulated cascode transistors is presented here. High gain pseudo-differential auxiliary amplifiers are used to implement the in order boost output impedance of open-loop op-amp. Both stages operate class AB mode. The proposed has been simulated 130nm commercial CMOS process technology...

A fully-differential seventh-order 0.05° equiripple linear phase low-pass filter based on multiple loop feedback (MLF) leapfrog (LF) topology is presented for read/write channels. The filter is designed and simulated with the proposed fully balanced, highly linear operational transconductance amplifier (OTA). This OTA contains two complementary differential cross-coupled input pairs and a pair ...

In this paper, a low-power adaptive low noise amplifier (LNA) is presented. The LNA is based on a bipolar cascode topology, uses inductive source degeneration and emitter area scaling to achieve noise and input-impedance matching simultaneously. The input impedance and the noise factor were simulated as function of the bias collector current and the results show that both are approximately cons...

In this paper, a formal design approach for the differential cascode voltage switch with pass gate (DCVSPG) logic is presented. This permits the design of any combinational logic function by the use of a k-map or by a modified QuineMcCluskey algorithm. The basic design approach used is based on pass logic and shows that a DCVSPG logic gate designed with minimum number of transistors may not alw...

In this paper we propose a design path for optimization-based device sizing of analog circuits. The design path offers an efficient and reliable way to implement high-performance analog integrated circuits without the explicit knowledge of an experienced designer. A key feature is that the partial cost functions are generated directly from the circuit topology. To demonstrate the functionality ...

The rapid growth of the hybrid electric vehicles (HEVs) has been driving the demand of high temperature automotive electronics target for the engine compartment, power train, and brakes where the ambient temperature normally exceeds 150°C. An operational transconductance amplifier (OTA) is an essential building block of various analog circuits such as data converters, instrumentation systems, l...

This paper presents the evaluation of heat generation behavior and related thermal measurement analysis of packaged high-power AlGaN/GaN high electron mobility transistors (HEMTs) cascaded with low-voltage MOSFET and SiC SBD. Since thermal management is extremely important for high power packaging, a hybrid integration of the GaN HEMTs onto a DBC substrate and metal case is proposed. We investi...
