Abstract :
All electrostatic discharge (ESD) pad protection structures have a nonlinear capacitor associated with a reversed biased p-n-junction. This paper discusses the distortion introduced by this nonlinear input capacitance given a finite signal source impedance and proposes a bootstrapped circuit to alleviate the problem. Experimental results are also presented
