A simple class-AB transconductor in CMOS

  title={A simple class-AB transconductor in CMOS},
  author={Bradley A. Minch},
  journal={2008 IEEE International Symposium on Circuits and Systems},
In this paper, we present a simple class-AB CMOS transconductor, which is based on Delbriick's bump/antibump circuit, whose differential output current is an expansive nonlinear function of its differential-mode input voltage. We describe the operation of the new transconductor qualitatively and derive an analytical model of its output currents from the Enz-Krummenacher-Vittoz (EKV) model of the MOS transistor. We also provide experimental measurements of the DC transfer characteristics of a… CONTINUE READING
