Abstract
A supply circuit for providing pulses of current has a current source, a reference voltage source for controlling magnitude of the current, and a current switch for controlling whether or not the current passes through a load. Also, there is a switch control signal terminal for controlling the current switch, and glitch compensation elements including at least one capacitance circuit and associated capacitor drive circuit for feeding a variable correcting voltage back to the reference voltage, and a controller to control said variable voltage.
Claims13
A supply circuit for providing pulses of current, the circuit comprising a current source, a reference voltage source for controlling magnitude of current delivered by the current source, a current switch for controlling whether or not said current passes through a load, a switch control signal terminal for controlling the current switch, and glitch compensation elements including at least one capacitor and associated drive circuit for feeding a variable correcting voltage to the reference voltage source, and a controller to control said correcting voltage in response to one or more parameters of the circuit, and wherein the glitch compensation elements comprise a plurality of drive elements, each connected in series with a capacitor for feeding a correcting voltage back to the reference voltage, the number of drive elements to operate at any time being dependant on an output of the controller.
