Abstract

This paper introduces a Switched-current Analysis Program (SIAP) that can perform both transient and frequency domain analysis of switched-current (SI) circuits. The program uses sparse matrices to reduce storage requirements and computation time. Transient analysis is performed using the large signal MOSFET model and the frequency domain analysis uses the small signal MOSFET model that includes all parasitic capacitance. All devices are modeled in a manner comparable with HSPICE and include almost all nonidealities, such as nonideal switches, clock feedthrough, channel-length modulation and transistor parasitic capacitors. Multiple inputs are allowed in both the transient and frequency domain analysis, thus differential circuits can be easily analyzed
