Power-off, loop-through return-loss with negative capacitance |
摘要 |
An improved power-off, loop-through return-loss characteristic for a current feedback operational amplifier is provided by adding a positive feedback capacitor between the input and output of the operational amplifier. The positive feedback capacitor results in a negative capacitance input impedance for the operational amplifier that cancels stray capacitances at the input.
