The paper proposes a high linear CMOS continuous-time common-mode feedback circuit. Theoretical analysis and SPICE simulation results are provided. Two circuit applications of the proposed configuration, one is the fully differential folded-cascode op-amp, the other is the Multiply-by-Two circuit which is the key component in the popular 1.5bit/stage pipelined ADC are designed. The Comparison results show that the new configuration has attractive characteristics concerning their implementation in high linear analog integrated circuits
