Balanced offset compensation circuit |
摘要 |
Balanced offset compensation is provided for a differential amplifier circuit. Two sets of three switches are employed between respective inputs and outputs of the differential amplifier to shunt the outputs to the input terminals during auto-zeroing phase. By opening and closing different combinations of the switches during auto-zeroing and operation phases, differential degradation due to unbalanced leakage currents is substantially reduced.
