Abstract :
An implementation of a discrete Hilbert transformer based on half-band filters using switched-current (SI) techniques is proposed. Structurally, all-pass networks were used to build a system with very low sensitivity to transistor mismatch. A sensitivity simulation is presented to validate the proposed circuit.
