Patent abstract
A transimpedance amplifier (TIA) circuit usable for burst mode communications is provided. The TIA circuit includes a TIA stage, a limiter-amplifier, and a DC restoration loop. The invention overcomes problems of the prior art relating to burst communications, such as a DC level in the output signal which can change from burst to burst and a duty-cycle distortion in large signals. This is achieved by using a DC restoration loop that ensures achieving zero DC potential within variable acquisition periods.
