초록
A loop stability compensation technique for continuous-time common-mode feedback (CMFB) circuits is presented. A Miller capacitor and nulling resistor in the compensation network provide a reliable and stable operation of the fully-differential operational amplifier without any performance degradation. The amplifier is designed in a 130 nm CMOS technology, achieves simulated performance of 57 dB open loop DC gain, 1.3-GHz unity-gain frequency and 65째 phase margin. Also, the loop gain, bandwidth and phase margin of the CMFB are 51 dB, 27 MHz, and 76째, respectively.
