Abstract:
A voltage level translator circuit for translating an input signal referenced to a first voltage supply to an output signal referenced to a second voltage supply includes an input stage for receiving the input signal, the input stage including at least first and second nodes, a voltage at the second node being a logical complement of a voltage at the first node. A load circuit is coupled with the input stage, the load circuit being operative to at least temporarily store a signal at the first and/or second nodes which is indicative of a logical state of the input signal. An output stage connected with the second node is operative to generate an output signal which is indicative of a logical state of the input signal. The voltage level translator circuit further includes a compensation circuit connected with the output stage and operative to balance pull-up and pull-down propagation delays in the voltage level translator circuit as a function of a voltage at the first node.
