Abstract: In an example, a system and method are disclosed for providing a single control law that is operable to regulate both small-signal, steady-state operation, and large-signal transients of a switching regulator. The control law is based on detecting a zero-crossing of capacitor current, and projecting in advance a turning point for either ramping up or ramping down capacitor voltage at a target voltage. Certain embodiments may realize the control function in high-speed analog components, although certain other embodiments may implement the same or a similar control law in a digital controller.

Abstract: Electrical networks are formed to produce an approximation of at least one desired performance characteristic, based on the recognition that fabrication variations introduce slight differences in electronic sub-networks which were intended to be identical. These fabrication differences are turned to an advantage by providing a pool of sub-networks, and then selectively connecting particular combinations of these sub-networks to implement networks that approximate the desired performance characteristics. The sub-networks are of like kind (e.g., resistors) and have a like measure.
