A continuous time common mode feedback (CMFB) technique for sub 1-V analog circuits using the bulk PMOS dynamic threshold @P-DTMOS) technique is presented. The proposed method is used in a 0.8V folded cascode amplitier. The amplifier with embedded CMFB is implemented in 0.18 um CMOS technology. The measurement data as well as simulation results are presented in this paper. The measurement results show that this technique improves the CMRR by 12 dB and helps reduce the common mode errors caused by process or environmental variations.
