Abstract
An analytical expression for HD3 (third harmonic distortion) due to the input-dependent, non-linear ON resistance of the MOS switch in a MOSFET-C sample and hold circuit is developed. The developed expression is suitable for hand calculation, and for a given target value of HD3, it can be used for an initial design of the MOS switch. The accuracy of the developed expression has been verified through simulation in 0.18 μm and 0.25 μm CMOS processes.
