High-speed, low-power input buffer for integrated circuit devices

A high-speed, low-power input buffer for an integrated circuit device in which the input voltage (VIN) is coupled to both a pull-up and a pull-down transistor. In accordance with a specific embodiment, the input buffer utilizes a reference voltage input (VREF) during a calibration phase of operation...

Zusammenfassung:A high-speed, low-power input buffer for an integrated circuit device in which the input voltage (VIN) is coupled to both a pull-up and a pull-down transistor. In accordance with a specific embodiment, the input buffer utilizes a reference voltage input (VREF) during a calibration phase of operation but not when in an active operational mode. A maximum level of through current is supplied when VIN=VREF with lower levels of through current at all other VIN voltages. In an integrated circuit device incorporating an input buffer as disclosed, two (or more) input buffers may be utilized per device input pin.
