Patent ID: 8508519

Claim:
An active level shift (ALS) driver circuit comprising: a first inverter receiving and inverting a gate signal to output a first inverted signal; a second inverter receiving and inverting the first inverted signal to output a second inverted signal; a third inverter receiving and inverting the second inverted signal to output a third inverted signal; a transmission gate receiving the second inverted signal at a first control terminal and receiving the third inverted signal at a second control terminal, the transmission gate being turned on when the third inverted signal is at a low level and being turned off when the third inverted signal is at a high level, the transmission gate outputting a first power signal to an output terminal of the active level shift (ALS) driver circuit when turned on; and a transistor receiving the third inverted signal, the transistor being turned on when the third inverted signal is at a high level to output a second power signal to the output terminal of the active level shift (ALS) driver circuit.
