Accurate BandGap Voltage/Current Reference Generator

Overview

CT20307 is an accurate reference voltage generator.

In order to achieve a total error <2%, the amplifier in the bandgap core block implements an offset cancellation circuitry.

Reference voltage thermal drift is minimized by means of 4 bits trimming so that the voltage reaches the “golden point”.

CT20307 includes reference currents generators, both using an internal accurate 4-bits trimmed resistor.
