Differential amplification system

Abstract

A differential amplification system for receiving first and second input signals, and for generating first and second differential output signals, the differential amplification system comprising a differential amplifier configured to receive the first input signal and the second input signal, provide a first output current at a first current channel, and provide a second output current at a second current channel, a cascode stage configured to receive the first and second output currents, and generate the first and second differential output signals, a detector configured to detect when the first output current flowing through the first current channel meets a first condition, and/or detect when the second output current flowing through the second current channel meets a second condition, wherein a current sink stage configured to redirect at least a portion of the first output current and at least a portion of the second output current away from the cascode stage when the first condition is met by the first output current, and/or redirect at least a portion of the first output current and at least a portion of the second output current away from the cascode stage when the second condition is met by the second output current, wherein the first condition is met by the first output current when the first output current falls below a first threshold current value and/or the first output current rises above the first threshold current value, and the second condition is met by the second output current when the second output current falls below a second threshold current value and/or the second output current rises above the second threshold current value.
