Title: Broad band amplifier
Inventor: HASE HIDEKAZU
IPC: H03F1/42
Filed: 1992-01-29
Abstract: PURPOSE:To obtain the broad band amplifier with a high gain by connecting an inductor between a source for amplifier transistor (TR) and a gate of a TR connected in series between a signal amplifier TR and a resistor. CONSTITUTION:The load of a signal amplifier TR 1 is higher at a high frequency till an output capacitor of the TR 1, an input capacitor of a TR 2 connected in series with the TR 1 and an inductor 4 are resonated. Furthermore, in order to make the gain of the amplifier flat over a broad band from a low frequency till a high frequency, a signal amplified across a load resistor 3 is amplified by a TR 5. Then a signal amplified from a load resistor 6 is fed back to a gate of the TR 1 by a capacitor 7 and a feedback resistor 8. Since the input impedance of the TR 5 amplifying the feedback signal is high, the effect given onto an amplifier circuit comprising the TRs 1, 2, the inductor 4 and the load resistor 3 is less and feedback is applied over a broad band.
