Abstract
In this paper a low power-low voltage operational transconductance amplifier and capacitor (OTA-C) oscillator based on a CMOS transconductor is proposed. The frequency of proposed VCO is controlled by adaptive neural network. OTA-C uses output cross coupled and interpolation. In this paper, a frequency tuning circuit for VCOs is introduced, so that the final relationship between oscillating frequency and input voltage is fixed and independent of the non-idealities. The adaptive neural network is applied for control of nonlinear parameters. The circuit has been fabricated in a standard 0.13mum CMOS process. Simulation results show a frequency tuning range from 52 to 164 MHz. The circuit uses 2V power supply with maximum 1.8 mW power consumption
