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...

The cascode NMOS architecture has been tested by the Human Body Model (HBM), Machine Model (MM) and Transmission Line Pulse Generator (TLP) in this paper. For the TLP, detailed silicon data have been analyzed well in many parameters, such as the first triggeringon voltage (Vt1), the first triggering-on current (It1), the holding voltage (Vh), and the TLP I-V curve. Besides the above three kinds...

A cascode CMOS low noise amplifier (LNA) is presented along with the used design methodology and measurement results. The LNA works at 2.4 GHz with 14.5 dB voltage gain and 2.8 dB simulated noise figure (NF). Powered from a 1.8 V supply, the core measured current consumption is 2.76 mA. An output buffer was designed to match a 50 Ω load and its current consumption is 5.5 mA. The technology used...

Typical parameters are maximum transducer gain, output power , low noise, circuit stability. Here a LNA is designed to obtain an optimum gain with minimum.

We present an area-efficient and low-power four-channel 25-Gb/s trans-impedance amplifier for Rx analog front-end (Rx-AFE) on optical receiver. The proposed circuit features a local negative-feedback (TIA) to expand the bandwidth. TIA post-amplifier use regulated cascode (RGC) topology two differential stages with inductive peaking bandwidth extension technique acquire 19.6 GHz of -3 dB 53.3 dB...

In this work, the factors affecting breakdown voltage of Si-GaN monolithic heterogeneous integrated Casccode FET fabricated by transfer printing were investigated. These two are avalanche resistance Si device and thickness SiN electrical isolation layer. Two kinds structures, MOSFET laterally-diffused (LDMOSFET), designed to study effect devices on characteristics Cascode FET. The layer was ana...

Tower mounted amplifiers (TMA) serve to lower the system noise figure (NF) in cellular base-stations. For performance reasons, the TMA is located as near to the receiving aerial as practical and has to be connected to the rest of the radio at the tower’s base by a long run of coaxial cable. The parameters critical to TMA performance are low NF for reasons of optimizing coverage area, high gain ...
