| Abstract: | unit-gain compensation ceil and pseudo-ESR (equivalent serial resistor of load capacitor) power stage have been realized by this controllable resistor.Their advantages and limitations are discussed and verified by simulation results. |
| Keywords: | controllable resistor pole-zero tracking single-Miller-capacitor with nulling resistor unit gain compensation cell pseudo-ESR power stage |
