Non-switched capacitor offset voltage compensation in operational amplifiers |
摘要 |
A method for reducing offset voltage in an operational amplifier without the need for switched-capacitors, includes introducing a tapped resistor chain between the common connected terminals of the transistors of the input differential pair of the operational amplifier and connecting the tail current source/sink of the differential amplifier to a selected tap of the resistor chain. The invention further provides an improved operational amplifier in accordance with the above method.
