Abstract
Low-power high-speed optical receivers are required
to meet the explosive growth in data communication systems.
This paper presents a 26 GHz transimpedance ampli fier (TIA)
that employs a transformer-based regulated cascode (RGC) input
stage which provides passive negative-feedback gain that enhances
the effective transconductance of the TIA’s input common-base
transistor; reducing the input resistance and isolating the parasitic
photodiode capacitance. This al lows for considerable bandwidth
