Abstract
A new low-voltage current-mode multifunction cell for analog signal processing, is presented in this paper. The proposed cell is based on sub-threshold MOS translinear (MTL) principle and consists of six matched NMOS transistors. Square-rooting, exponential and logarithmic functions are computational current-mode circuits that are designed using the proposed cell. The designed functions are simulated by HSPICE simulator in TSMC 0.18 µm (level-49 parameters) CMOS technology. Post-layout simulation results plus Monte Carlo analysis verified the functionality and superiority of the proposed circuits. Simulation results of the current-mode square-rooting circuit with 1-V DC supply voltage show that the maximum nonlinearity as 2.8%, the −3dB bandwidth as 32.95 MHz and the maximum power consumption as 520 nW.
