Abstract :
A new BiCMOS monolithic automatic gain control (AGC) amplifier with wide dynamic range is described. The forward gain path has 120 kΩ transimpedance, 140 MHz bandwidth, input noise current spectral density of 1.17 pA/√Hz and input signal current handling capability of 4 mA. An on-chip peak detector incorporating a 25 pA current source yields AGC hold times in the millisecond range
