Abstract
An amplifier () has a differential input stage (). An output transistor () is connected to receive a single ended output developed by transistor. First () and second () current sources are connected to establish respective first and second currents in the input differential transistors () according to a predetermined ratio. First and second voltages are subtracted from the differential inputs (VM,VP) in respective differential amplifiers (), and the output is derived from the output transistor having a magnitude proportional to an inverse of a product of a square of the reference resistance, a carrier mobility, and an oxide capacitance.
