ABSTRACT:
An improved voltage level shifting circuit is provided that employs a reference voltage translation circuit having its input at a fixed reference voltage, to bias the operating point of a substantially similar signal voltage circuit. The reference circuit generates a bias current in response to the reference voltage which is coupled back to buffers in the reference and signal translation circuits. The bias current maintains the operating point of the signal translation circuit close to the switching point determined by the reference voltage.
