Abstract
Techniques of bias-current re-utilization, self-biasing and signal superposition for low-voltage analog circuit designs are presented in this paper. When these techniques are adopted in a three-stage active-feedback compensated amplifier by using a self-cascode common-gate structure, the circuit complexity of the amplifier is simplified. In addition, the power consumption, parasitic capacitance and systematic offset voltage of the amplifier can be greatly reduced. The effectiveness of the proposed design methodologies is verified by remarkable HSPICE simulation results.
