ABSTRACT:
In an amplifier circuit a first and a second transistor and a load resistor are connected between supply terminals. An input terminal receives an input signal, comprising two signal components having, respectively relatively high and low frequencies, for applying said input signal to the second transistor. The base of the first transistor is decoupled by a capacitor at the high frequency only which results in the first transistor amplifying the high frequency component while the second transistor amplifies the low frequency component.
