A Low-Power, 26-GHz Transformer-Based Regulated Cascode Transimpedance Amplifier in ${
m 0.25}mu$ mSiGe BiCMOS Conference Paper

abstract

• A 26 GHz transimpedance amplifier (TIA) with transformer-based regulated cascode (RGC) input stage is proposed and analyzed. The transformer enhances the effective transconductance of the TIA's input common-base transistor; reducing the input resistance and providing considerable bandwidth extension. The TIA is implemented in a 0.25m BiCMOS technology. Measurement shows the single-ended transimpedance gain of 53dB with -3dB bandwidth of 26 GHz. Total chip power, including an output buffer, is 28.2mW from a 2.5V supply; while core TIA power is 8.2mW. The measured average input-referred noise current spectral density is 21.3 pA/Hz. Total chip area, including pads, is 960mx780m. 2011 IEEE.
