This paper presents the design, implementation and measurements of a BiCMOS integrated tunable Low Noise Amplifier for 5 GHz WLAN applications. It consists of a cascode gain cell, noise and power matched to a 50 Ω input source, and power matched to a 50 Ω load. In order to broaden the available bandwidth, the output matching network is modified by means of a shunt varactor, thus allowing the tu...

A pressure sensor demonstrator has been designed and mounted using a simple analog-digital BiCMOS converter and a capacitive Silicon–Pyrex sensing cell. The measurements as a function of pressure and temperature have enabled to evaluate the efficiency of a ratiometric scheme to self-compensate thermal drifts and nonlinearities. The best demonstrator is characterized by a thermal coefficient of ...

A low distortion low-voltage BiCMOS OTA with wide gm adjustment range and constant input range is presented. It is based on a highly linear voltage-to-current converter input stage merged with translinear loops that implement linear electronically programmable current mirrors. Experimental results are provided that confirm the characteristics of the proposed OTA with a single 1.7V supply, 1.2V ...

This invited paper reviews the progress of silicon–germanium (SiGe) bipolar-complementary metal–oxide–semiconductor (BiCMOS) technology-based integrated circuits (ICs) during last two decades. Focus is set on various transceiver (TRX) realizations in millimeter-wave range from 60 GHz and at terahertz (THz) frequencies above 300 GHz. article discusses development SiGe technologies ICs with latte...
