If the needed voltage-gain of a sample-and-hold amplifier is an integer, an alternative way of increasing the magnitude of the output signal can be used.EBSCO_bspEDNŠtofkaSlovakMariánSlovak
In the first approach, the user can subtract the two input signals with an instrumentation amplifier whose output links to an input of a classic sample-and-hold amplifier. Despite of the advantage of requiring no external resistors for a gain-of-one differencing instrumentation amplifier, this ...
A correlated double sampled/programmable gain amplifier (CDS/PGA) is disclosed which is operable to precondition a CCD output analog signal. The CDS/PGA includes an operational amplifier that is configured in a sample hold operation. The single-ended input is first clamped by a switch () to cl...
Sample and hold amplifier in which the held signal is shown as a voltage at a capacitor, the other signals being repésentés form of currents. A summing node, the input current and a feedback current are summed so as to produce a difference current. In the tracking mode, said difference...

A CMOS fully differential high gain-bandwidth (GBW) operational amplifier applied in a sample-and-hold (S&H) circuit is presented in the paper. High bandwidth and phase margin of the amplifier are obtained by combining two compensation techniques: Miller compensation and Feedforward compensation. In...
