The input section includes a first input unit and a second input unit and generate a first output signal that is indicative of the first input signal and a second output signal that is indicative of a level of the second input signal. The comparing section is coupled with the input section and compares the first output signal and the second output signal to responsively generate a result. The comparing section includes a first comparing unit and a second comparing unit. The control section is coupled with the input section and the comparing section. Furthermore, the control section activates, when receiving an initial load signal, the first input unit, the second input unit, the first comparing unit, and the second comparing unit. Moreover, the control section deactivates, before receiving a second load signal, at least one of the first input unit and the first comparing unit when the first output signal is greater than the second output signal. In addition, the result generated by the comparing section is indicative of a level of the first output signal.

摘要： A winner-take-all (WTA) circuit apparatus for comparing two current inputs from a WTA circuit to a threshold current to create a reject signal, to assist in the decision criteria of a winner-take-all network. The circuit compares the two input currents from the WTA circuit by using NMOS transistors which perform electrical mathematical functions by manipulating the currents. The end result is that the difference of the two currents is compared with a reference current and a voltage level is outputted. The reference current is adjustable, and the invention also provides a WTA circuit with weighted inputs, and the ability to select between a 1-WTA, and a 2-WTA configuration. The invention therefore solves the problems of prior art by being capable of properly selecting current levels or rejecting current levels which are too close in value, with a voltage reject signal.
