Abstract

PURPOSE:To determine a frequency band of an electronic circuit with simple circuit constitution by connecting an emitter of a transistor (TR) to a ground terminal via a resistor and the parallel connection of an inductor and a capacitor. CONSTITUTION:The TR Q1 is used for the titled amplifier, where the emitter is connected to a ground terminal via a current series feedback resistor R1 and the parallel connection of the inductance L1 and the capacitor C1 and a voltage parallel feedback resistor R2 is connected between the collector and base. The current series feedback resistor R1 and the inductance L1 and the capacitor C1 connected in parallel connected to the emitter of the TR Q1 form a current series feedback circuit. Thus, it is not required to employ a band-pass filter or a notch filter to split the band into two and the titled amplifier is constituted inexpensively with simple constitution.
