Özet

In this paper, a method for extending the bandwidth of a symmetrical operational transconductance amplifier (OTA) circuit is proposed. Resistive compensation technique is applied to all current mirrors of the symmetrical OTA circuit. A passive resistor is connected between the gate and the drain of each primary transistor of the current mirrors in the symmetrical OTA structure. The performance of the proposed OTA with extended transconductance bandwidth is analyzed by implementing filter structures. The advantage of using the resistive compensation technique is demonstrated. The proposed symmetrical OTA and the filters are simulated with LTSPICE by using TSMC 0.18 mu m CMOS process parameters.
