A Low Power, High Input Dynamic Range and High Precision Current-Mode Loser-Take-All Circuit
In this paper, a current-mode loser-take-all (LTA) circuit is proposed. The proposed circuit has a high input dynamic range and offers very high precision. The circuit maintains high precision not only at low currents close to zero but also at currents in the range of several hundred microamperes. Additionally, the power consumption per cell in the proposed circuit is very low. The circuit is designed using 180 nm technology, operating at a supply voltage of 1.8 V, with a power consumption of 18 µW per cell in a 3-input structure. In the proposed circuit, the maximum error occurs at an input range of 200 µA and an input frequency of 2 MHz, which is 1.3%.
