TRANSCEIVER DRIVER WITH PROGRAMMABLE EDGE RATE CONTROL INDEPENDENT OF FABRICATION PROCESS, SUPPLY VOLTAGE, AND TEMPERATURE

摘要

A transceiver driver for shaping an output signal includes one or more capacitive elements designed to manipulate the current applied to the control node of the driver's output transistor. The capacitive elements may be one or more capacitors coupled to an inverter branch that provides turn-on and turn-off potential to the gate of the output transistor. The capacitive elements act to charge or discharge the transistor's gate gradual in a highly programmable way so as to make the driver substantially independent of fabrication, supply voltage, and operating temperature vagaries.
