<p>The input buffer (200) of a low-voltage technology integrated circuit (IC) has a buffer transistor (M1) adapted to receive an input signal at the gate (G) of the input buffer. The channel nodes of the input buffer are connected to other circuitry (e.g., the low-voltage bias voltage (VDD) and a current source (I1)). With such an input buffer, the low-voltage circuit can safely receive a relatively high input voltage. As such, the low-voltage circuit can be interfaced to and safely operated in conjunction with relatively high-voltage technology circuitry. In one implementation, IC circuitry of existing 5V technology can be safely used with IC circuitry of a new 2.5V technology having an input buffer of the present invention. <IMAGE></p> |
