Abstract
In this paper new ELIN systems implemented by using CMOS transistors in weak inversion operation are presented. The proposed systems exploit the exponential-law characteristics of the subthreshold CMOS transistors. New operational transconductance amplifiers in CMOS technology, providing elementary tanh and sinh/cosh functions with high accuracy are proposed. These elementary cells are used to design first order CMOS ELIN filters. For a bias current of 1A, the dynamic range of the predistorted input voltage is 220mVpp and the current consumption is about 20uA from a 3.3V supply voltage. The simulations performed in 0.18um CMOS technology confirm the theoretically obtained results. |
