---|---|---|
This paper presents a highly linear Gilbert cell OTA by cancelling the second order transconductance derivative (gm")of nMOS transistors near threshold voltage using the technique of multiple gated transistors. This gives rise to 5 dB improvement in IIP3 of OTA, using a 0.13 mu m CMOS technology with 1.2V supply. Simulation results and analytical relations for THD and IIP3 in OTA illustrate the tradeoffs between linearity, bandwidth, and power dissipation. System level simulation of a non-coherent UWB receiver, with this OTA as a Gm-C integrator in receiver structure, illustrates an improvement of BER from 3e(-2) to 1e(-3). The power consumption, IIP3, and transconductance in OTA are 0.62mW, 20.5 dBm, and 156 mu A/V, respectively. |
