Abstract
A low drift sample and hold circuit is disclosed comprising a transconductance input buffer coupled at its output to a plurality of CMOS inverters through a respective plurality of CMOS switches. The appropriate switches are momentarily addressed by a micro-processor while applying a respective input value to the buffer. The buffer is de-activated prior to the opening of the switch to prevent errors between the sampled and held values.
