PRBS Test Signature Analysis of Switched Current Circuit

A PRBS tested signature analysis method that is based on the excitation of the switched current circuits with pseudo random sequence and the subsequent analysis of the captured response is proposed in this paper. It has taken into account of the connection between special structural problems and CMOS's parameters in switched current circuits such as the drain-gate capacitance Cdg, gate-source capacitance Cgs and transconductance gm. The fault detection capabilities of the test and data analysis methods demonstrated by applying them to variant switched current filter circuit.
