Constant edge rate output driver |
摘要 |
In a circuit and method for adjusting rise-and-fall-time changes in an output driver signal due to changes in temperature, process or voltage, the driver output voltage is monitored and current flow through a constant load resistor adjusted as the voltage changes. The current may be adjusted by controlling the gate-source voltage on a transistor. The gate voltage on the transistor may also be used to adjust the power supply to pre-drivers of the output driver.
