This paper presents an efficient modeling and frequency domain analysis method for analyzing the effect of the clock feed-through and charge injection in switched current circuits. The effect of clock feed-through is analyzed by modeling the clock signal using two constant voltage sources that are switched periodically. The charge injection is depicted using two impulse charge sources that inject charge into both the source and drain terminals of MOS switches when the devices undergo a ON-OFF transition. In addition, both parasitic capacitances and channel resistance of MOS switches are considered. The analysis is carried out using the approach for periodically switched linear circuits. A computer program has been developed. Simulation results on example circuits are presented.
