Abstract
A simple negative transimpedance amplifier is proposed. Because of inherent low input and output impedance, the frequency response is higher than that of the traditional operational amplifier. Using feedback, the operation frequency of amplifier can be extended. By using a simple feedback resistance, the amplifier¡¦s output level is stabilized without using common-mode feedback.
The negative transimpedance amplifier as a common active element is versatile. The characteristics of these application circuits are dominated by the passive elements of the circuits. In the transimpedance-C bandpass filter and transimpedance-C lowpass filter, the , , and Q factor can be tuned. Owing to the negligible loading effect of the transimpedance amplifier, the single stage Rm-C biquad can be cascaded to high order filters. In the voltage controlled oscillator, the oscillation frequency can also be tuned.
