Abstract
An amplifier for a semiconductor circuit provides two circuit paths between VCC and ground, each including the source-drain path of a corresponding primary transistor. Two inpedances are coupled to respective inputs. The primary transistors are kept in saturation so that the voltage differential between the inputs is minimized but a large voltage differential is developed at outputs located along the two circuit paths. Also, a clamp circuit has a common node coupling the gate electrodes of the primary transistors together. Secondary transistors are included to mimic voltage changes on either input.
