ABSTRACT:
In many high voltage circuits, it often needs to shift the logic voltage level to keep the circuit normal operation. In the class-D amplifier circuitry, it needs to shift the voltage level of pulse width modulation (PWM) signal to control the connecting of different power switches. In other applications, such as a driver to drive amplifier of an audio device, it also needs a level shift circuit to maintain the circuitry in normal voltage operation. Therefore, this invention is to provide a novel level shift circuit with high performance, low cost and low power dissipation characteristics.
