AbstractA BiCMOS rail-to-rail operational amplifier capable of operating from supply voltages as low as 1.W is presented. A new technique of achieving a rail-to-rail input common mode range us'ing a bipolar input stage is developed. The new technique avoids the use of complementary pairs at the input and thus avoids complicated schemes for monitoring the constant g,?, . The resulting variation ...

We present, in this paper the mathematical approach for optimization nanometric thickness of the SiGeC base heterojunction bipolar transistors (HBTs), realized in BiCMOS industrial process. However, use of these components in applications microwave radio frequencies implores the use of complex structures shrinking. The base SiGeC is the active part of the transistor, the optimization of the nan...

A sample-and-hold amplifier designed for the front end of high-speed low-power analog-to-digital converters employs a BiCMOS sampling switch and a low-voltage amplifier to achieve a sampling rate of 200 MHz while allowing input/output voltage swings of 1.5 V with a 3-V supply. The circuit also incorporates a cancellation technique to relax the trade-off between the holdmode feedthrough and the ...

Very Large Scale Integration (VLSI) Systems, 3 (3), 437 (September 1995). Merged Current Switch Logic (MCSL) and Differential Cascode Voltage Switch Logic (DCVSL) are two common structures for differential BiCMOS logic family, that have several potential applications in high-speed VLSI circuits. This paper studies the fault characterization of these BiCMOS circuits. The impact of each possible ...

“More Than Moore” functional diversification by combining different technologies is enlarging the spectrum for embedded system applications. In this paper we focus on the monolithic integration approach of optical components into the front-endoff-line (FEOL) to combine electronics and photonics (Si Photonics), and of MEMS (microelectro-mechanical systems) into the back-end-offline (BEOL) of SiG...

In this paper, we present three monolithical microwave integrated circuits (MMIC’s) that potentially may be used in the receiver front-ends of future wide-band multi-purpose array antennas, for example. Two low-noise amplifiers (LNA’s) and one tunable filter have been designed in a 0.35μm bipolar complementary metal oxide semiconductor (BiCMOS) technology containing high frequency silicongerman...

In this work we present a high-speed optical receiver with external large-area photodiode. The optical receiver is realized in 0.35μm SiGe BiCMOS technology. The input circuit is a two-transistor transimpedance amplifier using an common-emitter and an emitter-follower configuration. An external silicon PIN photodiode of a squared area of 0.25mm2 with a rise time of 0.4ns at 850nm light is used....

This paper describes precision techniques for the design of comparators used in high-performance analog-to-digita1 converters employing parallel conversion stages. Following a review of conventional offset cancellation techniques, circuit designs achieving 12-b resolution in both BiCMOS and CMOS 5-V technologies are presented. The BiCMOS comparator consists of a preamplifier followed by two reg...
