Abstract :
Experimental results are reported for an amplifier based on a little-known effect in MOS capacitors: a voltage sampled on the gate rises when the channel charge is pulled out. It is demonstrated that this phenomenon can be used to provide micro-power, low-gain, and low-noise signal amplification.
