Abstract
Official abstract text for this publication.
A current correction circuit ( 200 ) has an input ( 201 ) and includes: a first controllable current source ( 220 ) having an input connected to the circuit input for drawing a first current (I 220 ) from the circuit input; a differentiator ( 210 ) having an input coupled to the circuit input and having an output coupled to the first current source; and/or a second controllable current source ( 240 ) having an input connected to the circuit input for drawing a second current (I 240 ) from the circuit input; a voltage comparator ( 230 ) having a first input coupled to the circuit input ( 201 ), having a second input coupled to receive a reference signal (Vref), and having an output coupled to the second current source. The circuit is responsive to voltage changes by drawing first current pulses ( 221 ) from the circuit input, and/or to low voltages by drawing second current pulses ( 241 ) from the circuit input.
First claim
Opening claim text (preview).
The invention claimed is: 1. A current correction circuit, having an input and comprising: a controllable current source having an input connected to the circuit input for drawing a current from said circuit input; a signal edge detector circuit having an input coupled to the circuit input and having an output coupled to the controllable current source for controlling the operation thereof; wherein the circuit is responsive to a voltage edge at the circuit input by drawing a cur…
