HIGH SPEED LEVEL TRANSLATOR

摘要

A high speed VPP level translator circuit using thin-oxide field effect transistors (FETs) and methods of use are disclosed. The level translator includes a resistor divider and a one-shot circuit in parallel with the resistor divider. The one-shot circuit conducts to assist a transition from a first state to a second state, and is non-conducting during the transition from the second state to the first state.

主权项

1. A level translator, comprising:
a resistor divider configured to be switched on/off to provide an output of a low voltage and a high voltage; and a one-shot circuit comprised of an inverter chain and a pull-up stack of transistors in parallel with the resistor divider, the one-shot circuit conducting for a transition from a first state to a second state through a conduction path provided by the pull-up stack, and non-conducting for an opposite transition, wherein the one-shot circuit translates from the low voltage to the high voltage using the transistors arranged in parallel with a first resistor of the resistor divider and the inverter chain having outputs controlling gates of the transistors to provide a conduction path between an output level of the first resistor.
