In this paper, a CMOS OTA with a wide input voltage range and linearly tunable transconductance gain (gm) is presented. To achieve the linear control of transconductance, the bias current (IB) is squared by using the current squarer circuit before applying it into the main CMOS OTA. In addition, the source degeneration technique is used to extend the input voltage range. The frequency response ...

متن کاملNovel operational transconductance amplifier based on floating gate MOSFET tunable grounded resistor
The design of tunable operational transconductance amplifier with wide linear range has become increasingly challenging with the scaling in the power supply voltage. Use of control voltage for the purpose of tunning often results in narrow linear range. In recent years the use of voltage as a control parameter has even become more difficult with the reduced supply voltage environment. In this p...
