In this paper, a new scheme is proposed to completely cancel both signal-dependent and signal-independent charge injection errors in second-generation switched-current circuits. The n-step principle has been employed to suppress the signal-dependent distortion error while the circuit-replication technique has been adopted to simultaneously diminish the signal-independent offset. SPICE simulations have verified the feasibility and effectiveness of the proposed cell for tackling the charge injection problem. Major merits of the proposed cell include capability to meet high precision requirements and applicability to any second-generation switched-current circuit configuration.
