<p>An amplifier comprising a bipolar transistor with a non-linear load resistance (21) that increases the forward gain of the amplifier at high frequency. Voltage and thermal stability are provided by a chain of diodes (18) providing the input bias. Supply rail ripples introduced to the circuit via the input and via an output stage transistor (11), are in antiphase and the amplitude of the component introduced via the output stage transistor (11) can be tuned (Figure 3) by varying the load resistance on the output stage transistor.</p> |
