Multistage amplifier circuit with improved nested transconductance capacitance compensation |
摘要 |
<p>Inclusion of a current mirror circuit and differential amplifier in the input amplifier stage 10 and a current mirror circuit in the feed-forward amplifier stage 12 of the nested transconductance capacitance compensation multistage amplifier design provides a low-voltage multistage amplifier having less sensitivity to power supply voltage while retaining frequency domain advantages. The nested transconductance capacitance compensation multistage amplifier includes an input differential amplifier stage 10, a feed-forward amplifier stage 12, and an output amplifier stage 14. This design improves the power supply rejection of the multistage operational amplifier. <IMAGE></p> |
