Abstract
An analog current memory circuit includes a ramp current generator producing a ramp current; a storage transistor, a write-enable transistor, a charge pump transistor, a clock generator producing a clock signal having a first state and a second state, a comparator electrically coupled to the storage transistor and the ramp current generator, a controller electrically coupled to the comparator and the clock generator, and a switch electrically coupled to the controller and the ramp current generator. During the write phase, the controller produces a write-enable signal to turn on the write-enable transistor to produce a stored current in the storage transistor, the stored current being substantially equal to an input current to the analog current memory circuit. During the compensation phase, the switch electrically couples the ramp current generator and the storage transistor to the comparator.
