A Study on Closed-loop Characteristic of Negative-feedback Amplifier Based on OTA
Liang Chang-Hui · 2004
Closed-loop characteristic of negative-feedback amplifier based on OTA is studied by network method on the basis of a parameter. The results show that introducing negative feedback makes the change of closed-loop gain and closed-loop input as well as output resistance remain 1+AF in form, which agrees with the traditional voltage OP-AMP.
