摘要

A CMOS scalable high-speed current-mode asynchronous winner-take-all (WTA) circuit is described. The new WTA has improved resolution and operating speed compared to other current-mode WTA's, especially for large M, where M is the number of inputs. The proposed arrangement is, therefore, well suited to applications requiring large WTA systems where operating speed and resolution are important parameters e.g., vector quantization (VQ). Measurements show that the proposed circuit can resolve inputcurrents differing by less than 1μA with negligible loss of operating speed. Detailed measured results and simulations are presented.
