Abstract:
A sample and hold circuit providing rail-to rail equivalent output is described. The circuit includes a sample and hold amplifier containing two separate sets of sampling capacitors, one set is coupled to a PMOS transistor differential stage and the other set is coupled to an NMOS transistor differential stage. The differential stages drive a current mirror based push-pull output differential stage to provide an output signal with ranges equivalent to a rail-to rail output signal swing.
