This work focuses on the implementation of a thermistor-based power sensor for an operating frequency around 77GHz in a 0.35 m bipolar technology. As the sensor concept is based on DC substitution, absolute rms power levels can be derived which makes the sensor suitable for built-in self-test and calibration purposes. The error between the sensor results(More)
A transmitter with an output frequency range from 341 to 386 GHz is presented. Power output varies from 0.1 to -15.8 dBm along its operating range, while it remains above -2.9 dBm from 341 to 353 GHz. The high-frequency signal is generated using a wideband push-push voltage-controlled oscillator (VCO) with coarse and fine frequency tuning control, a 3-stage(More)
A wideband 148-188 GHz push-push voltage-controlled oscillator (VCO) is presented. The frequency tuning is performed using a varactor, and a variable inductor optimally designed for wide inductance tuning range. At a center frequency of 168GHz, a frequency tuning range of 40GHz (23.8%) is achieved, which is a record value for VCOs at this frequency range.(More)
A 9-81/38-189 GHz dual-band divide-by-2 dynamic frequency divider is presented. The band switching is performed by switching a capacitance using PIN diodes. To the best of the authors' knowledge, this is the first band switching dynamic divider reported so far at such high frequencies. The divider is based on the regenerative frequency division principle(More)
This work presents a power amplifier for automotive radar applications based on the differential cascode topology. The power amplifier is manufactured in a 130 nm SiGe BiCMOS technology. At 77 GHz, the peak power added efficiency is 16 % at an output power of 17 dBm. Furthermore, the linear gain is 14.2 dB and the maximum saturated output power reaches 17.5(More)
