Abstract
In an SRPP circuit, a transistor Q11 has a collector connected to a power supply terminal T13 through a resistor R11 and an emitter connected to the collector of a transistor Q12 having the same polarity as that of transistor Q11. The emitter of the transistor Q12 is connected to the ground. The collector of the transistor Q11 is connected to the emitter of a transistor Q13 having the polarity opposite to that of the transistor Q11, and the collector of the transistor Q13 is connected to the base of the transistor Q12. A bias voltage V13 is applied to the base of the transistor Q13. An input signal Vin is supplied to the base of the transistor Q11 to extract an output signal from a node between the emitter of the transistor Q11 and the collector of the transistor Q12.
