Abstract :
Integrated InGaP/GaAs HBT transimpedance amplifier (TZ) circuits were designed, fabricated and characterized. In this study, we propose using a capacitive-peaking (C-peaking) technique to increase the bandwidth of the transimpedance amplifier. Based on a Butterworth-type approach, we can easily enhance the bandwidth of the amplifier by this C-peaking technique without sacrificing its low-frequency TZ gain. The low-frequency transimpedance gain of our designed amplifier is 51.4 dBΩ, and the measured 3 dB bandwidth is enhanced from 9 GHz to 11.8 GHz
