ABSTRACT:
Method and circuitry for implementing low voltage input buffers using low voltage CMOS transistors are disclosed. Various novel circuit techniques enable the input buffer to safely receive and reliably detect input logic signals in the presence of overshoot or undershoot conditions. In a preferred embodiment, the source terminals of input transistors are biased such that the impact of overshooting or undershooting signals at the input terminal are drastically reduced.
