Abstract
A reference voltage source, relatively insensitive to changes in ambient temperature and supply voltage, utilizes a plurality of charge transfer amplifiers each having a temperature-stable amplification factor determined essentially by the ratio of two capacitances and independent of temperature-related factors. The amplifiers operate to provide a punch-through reference device with a constant current to cause generation of a stable reference voltage.
