Title:
VOLTAGE SHIFT CIRCUIT
Document Type and Number:
Japanese Patent JP3962383
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a voltage shift circuit which is capable of reducing a transition time, accelerating the transition, operating circuits with much lower input voltage, reducing a short-circuit current by accelerating the transition time, and achieving a power saving effect by reducing current consumption.
SOLUTION: The voltage shift circuit has a pair of p-type FET switches, a pair of n-type FET switches, an inverter, and a plurality of trigger circuits. The triggers are connected to the gates of high-voltage devices (n-type FET transistor switches) and the substrate region of the high-voltage devices, so that the trigger circuits can generate a trigger signal continuing for a period of time after receiving a low voltage control signal in order to change voltages on the substrates at circuit transition and further reduce the threshold voltages of the high-voltage devices to increase the transition speed of the circuit.
