Abstract:
Methods and structures for ensuring the highly linear discharge of a capacitor used for slew rate control of a power driving stage from a maximum voltage to a minimum supply voltage, such as ground. A voltage ramp generator uses a single cascoded current source to achieve the linear ramp-down.
