Programmable current source correction circuit |
摘要 |
A small and easy to fabricate programmable current source correction circuit. The correction circuit consists of a first current division circuit for establishing a reference current; a programmable correction current circuit for establishing the amount of correction current required; a second current division circuit for further reducing the reference current into smaller step or resolution; and a source-sink controlling circuit for determining whether the present invention is to operate as a current sink or current source. The present invention consists of substantially less number of circuit modules and can be fully integrated into a single chip which requires substantially smaller chip area and can operates at a substantially higher frequency compared to prior art.
