Abstract
A level shifting circuit includes negative voltage shifting circuitry including a first leg and a second leg. The first leg includes a first plurality of NMOS transistors in series with a first input node and a negative amplified voltage, and the second leg includes a second plurality of NMOS transistors in series with a second input node and the negative amplified voltage. The level shifting circuit further includes positive voltage shifting circuitry including a first plurality of high voltage transistors in series with a positive amplified voltage and an output node of the level shifting circuit, and a second plurality of high voltage transistors in series with a first intermediate node of the first leg of the negative voltage shifting circuitry and the output node of the level shifting circuit. The level shifting circuitry further includes input circuitry including a plurality of inverters.
