A 10b 120MS/s 45nm CMOS ADC Using A Re-Configurable Three-Stage Switched Op-Amp Young-Ju Kim 1, Kyung-Hoon Lee, Seung-Hak Ji1, Yi-Gi Kwon, Seung-Hoon Lee, Kyoung-Jun Moon 2, Michael Choi, Ho-Jin Park2, and Byeong-Ha Park2. The very high open-loop gain of the op-amp allows a wide range of feedback levels to be applied to achieve the desired performance. CR Download the SPICE file. net dictionary. These devices also feature integrated EMI filters to reduce high-frequency signal demodulation on the output. Eﬀects of Op-Amp Finite Gain and Bandwidth Open-Loop Transfer Function In our analysis of op-amp circuits this far, we have considered the op-amps to have an inﬁnite gain and an inﬁnite bandwidth. The following diagram shows the Wien bridge oscillator by using the IC74.
