Abstract
A process and circuitry for drawing current from a power source to produce a first operation, such as a Boolean operation, and reusing the current to generate a further operation. In other words, the current from the first operation may be used to perform a second or subsequent operation. This process is referred generally herein as current recycling.
Claims19
A circuit comprising:
- a first current steering stage;
- at least a second current steering stage;
- the first current steering stage, comprising a low voltage differential swing circuit, using a first current to drive a first output in respect to a first input;
- and
- the second current steering stage, using a second current from the first current steering stage, configured to drive a second output in respect to a second input.
2 more elements
A circuit comprising:
- a first circuit, including a first current steering stage comprising a low voltage differential swing circuit, adapted to receive a first supply current;
- and
- a second circuit adapted to receive a second supply current only from the first circuit;
- the first circuit adapted to produce a first output in response to a first input and the second circuit adapted to produce a second output in response to a second input.
1 more element
A process for operating circuitry comprising
- (a) providing a current to a first circuit including a first current steering stage comprising a low voltage differential swing circuit;
- (b) using, by the first circuit, the current for providing a first output in respect to a first input;
- (c) providing the current to a second circuit different from the first circuit;
- and
- (d) using, by the second circuit, the current for providing a second output in respect to a second input.
