Abstract :
A pole-zero simulator with a component sensitivity analysis function has been developed in order to achieve high-performance characteristics in analog circuits. The functions of this simulator include specifying the circuit components which determine pole-zero values and intensity computation for the influence of individual components on such circuit characteristics as DC-gain, unity-gain frequency, etc. This simulator provides very straightforward design flow. In an op-amp design example, frequency response is seen to improve greatly without trial and error
