Abstract
A low noise amplifier circuit is operable in two gain modes: high gain (approximately 15 dB) and low gain or attenuation (approximately −5 dB), with a number of gain paths. In the low gain or attenuation path, the frequency response is improved by adding a diode-connected transistor and a capacitor connected in series and operating as a filter, which effectively puts a pole (p=−1/R,C,) in the peak of the high frequency response.
