Minimum-energy sub-threshold self-timed circuits: design methodology and a case study
(2010) The 16th IEEE International Symposium on Asynchronous Circuits and Systems (ASYNC)- Abstract
- This paper addresses the design of self-timed energy minimum circuits, operating in the sub-VT domain. The paper presents a generic implementation template using bundled-data circuitry and current sensing completion detection. To support this, a fully-decoupled latch controller has been developed, which integrates the current sensing circuitry. The paper outlines a corresponding design flow, which is based on contemporary synchronous EDA tools, and which transforms a synchronous design, into a corresponding self-timed circuit. The design flow and the current-sensing technique is validated by the implementation of an asynchronous version of a wavelet based event detector for cardiac pacemaker applications in a standard 65nm CMOS process....

The chip has been fabricated and the area overhead due to power domain separation and completion detection circuitry
is 13.6 %. The improvement in throughput due to asynchronous operation is 52.58 %. By trading the throughput improvement, energy dissipation is reduced by 16.8% at the energy-minimum supply voltage. (Less)
