Abstract :
A nonsaturating TIA with 20mA input current overdrive and 48nA equivalent rms input noise current is described. The proposed TIA has a linear region for small input currents and a compressing one for high currents, which would otherwise saturate the TIA. The complete chip including the 50Omega driver occupies 1.24mm2 in 0.35mum SiGe BiCMOS technology.
