Abstract
In this paper a new approach for design of class-AB current-mode square-root
domain filters based on the electronically simulated translinear loop principle is presented.
FG-MOS transistors that operate in strong inverted saturation region are employed for
implementation of translinear loop circuit. The filter achieves immunity to body effect, low
circuit complexity, large input dynamic range, and also works in low voltage compared to
those reported before. With supply voltage 1.2V a dynamic range of 46dB at 1% THD is
achieved. Simulation results by HSPICE confirm the validity of the proposed design
technique and show high performance of the filter.

Abstract
In this paper a new synthesis for circuit design of Euclidean distance calculation
is presented. The circuit is implemented based on a simple two-quadrant squarer/divider
block. The circuit that employs floating gate MOS (FG-MOS) transistors operating in weak
inversion region, features low circuit complexity, low power (<20uW), low supply voltage
(0.5V), two quadrant input current, wide dynamic range and immunity from body effect. In
addition, this circuit is designed in modular methodology, leading to a very regular
structure. The circuit was successfully applied to the recognition of some simple patterns.
Simulation results of the circuit by HSPICE show high performance in the separation and
confirm the validity of the proposed technique.
