摘要:
A charge recovery driver is for a pair of loads, and includes first and second output nodes coupled to a pair of loads. During an initial phase, the first output node is grounded and the second output node is tied to the supply voltage. During a first phase, the first output node is coupled to the first tank capacitor and the second output node is coupled to the second tank capacitor. During a second phase, the first and second output nodes are coupled to one another. During a third phase, the second output node is coupled to the first tank capacitor and the first output node is coupled to the second tank capacitor. During a fourth phase, the first output node is coupled to the supply voltage and the second output node is coupled to ground. The third, second, and first phases are then repeated in that order.
