Abstract

See full text

This application relates to transimpedance amplifier (TIA) apparatus, in particular to a TIA apparatus suitable for receiving data using burst mode communication. The apparatus has a transimpedance amplifier configured to generate a first voltage based on a current at an input node for an input signal. A controlled voltage source, such as a dummy TIA, generates a second voltage based on a first control current. A controller is configured to collectively control the first control current and a second control current based on an indication of input signal magnitude. The first control current controls the second voltage which may be used as a slicing level. The second control current is subtracted from the current at the input node and can provide a DC restore current.
