  4. Abstract:
  5. A 1.5-V single supply, second order continuous-time bandpass filter, on a 0.6μm standard CMOS process is designed. The THD of the transconductor for a 0.7Vpp input, is -50dB at 10-MHz. In the proposed transconductor structure, the whole circuit, apart from a dc level-shifter based on a voltage doubler, is biased by a single 1.5-V supply. Due to this structure, a high current voltage doubler is not required and the whole filter draws less than 70μm current from this doubler making an on-chip voltage doubler feasible. Also, a new linear common-mode detector with high-frequency response is designed to stabilize the output common-mode voltage. © 2002 IEEE
