Abstract :
The relation between the output signal-to-noise ratio (SNR) and the input SNR is presented for the bandpass self-biased third-law amplifier with saturation, when the input is composed of sinusoidal carrier and zero-mean stationary narrowband Gaussian noise. It is found that significant improvement in the output SNR at low input SNR´s can be achieved by the self-biased third-law amplifier with saturation operated in class A. The results obtained are also verified experimentally.
