摘要：
The present invention provides an amplifier having cascade-connected first and second transistors, a constant current source for supplying an operating current to the first transistor, and a load resistor connected to the collector of the first transistor at one end and to a substantially constant voltage terminal at the other end. The amplifier arrangement of the invention removes the necessity of a large capacitance capacitor for noise suppression.
