摘要： A balanced differential transimpedance amplifier with a single-ended input operational over a wide variation in the dynamic range of input signals. A threshold circuit is employed to either or a combination of (1) generate a varying decision threshold to ensure a proper slicing over a wide range of input current signal levels; and (2) generate a bias current and voltage applied to an input of a transimpedance stage to cancel out a dependence of the transimpedance stage voltage input on input current signal levels.

摘要： A method and apparatus for compensating current leakage is disclosed. In the method and apparatus, a differential amplifier receives a first input signal and a second input signal and outputs a first output signal and a second output signal. The first output signal is filtered to obtain a first filtered signal. The first filtered signal is compared to the first input signal and a first compensation signal is outputted having a first voltage that is a function of a difference between a voltage of the first filtered signal and a voltage of the first input signal. Current leakage in the first input signal is compensated for using the first compensation signal.

摘要： A method and circuit are provided for implementing enhanced CMOS inverter based optical Transimpedance Amplifiers (TIAs). A transimpedence amplifer (TIA) includes a photo-detector, and the TIA is formed by a first TIA inverter and a second TIA inverter. The first TIA inverter has an input from a cathode side of the photo-detector and the second inverter has an input from an anode side of the photo-detector. A replica TIA is formed by two replica inverters, coupled to a respective input to a first operational amplifier and a second operational amplifier. The first operational amplifier and the second operational amplifier have a feedback configuration for respectively regulating a set voltage level at the cathode side of the photo-detector input of the first inverter and at the anode side of the photo-detector input of the second inverter.
