摘要

A supervoltage circuit has been described which uses a resistor divider as an input stage. The resistor divider decreases the dependancy of the supervoltage trip point on transistor threshold voltages (Vt). The stability of supervoltage trip point is significantly increased over traditional supervoltage circuits using diode connected transistors as an input stage. The supervoltage circuit can be included in any integrated circuit including memory devices.
