摘要： Power available to an integrator circuit is controlled so that relatively high power is provided during one phase of operation, such as during an interval when slewing in a device is expected and relatively low power is provided during another phase. In one implementation, increased power is provided by switching in parallel current mirrors when power demands are expected to be high, whether or not high power is actually needed in a particular interval. The techniques are particularly useful when applied to clocked integrator circuits.
