Abstract

PURPOSE:To make input sensitivity high extending over a wide frequency by providing two amplifiers having frequency characteristics corresponding to a frequency band to be used, and selecting and using one of them. CONSTITUTION:A low frequency waveform shaping circuit 1 includes a negative phase amplification circuit IL for a low frequency corresponding to the input signal of the reception frequency of a frequency band within 0.1 MHz-10MHz, and the series circuit of an inverter Il for limiting an amplitude. Then, a high frequency waveform shaping circuit 2 includes an inverse phase amplification circuit IH for a high frequency corresponding to the input signal of the reception frequency of the frequency band within 10-100MHz, and the series circuit of the inverter Ih for limiting the amplitude. In case that the frequency of the input signal Vi is 1MHz, for instance, if a low level value L is designated as a control signal Vc to a control terminal Tc, the inverted output signal Vc of the inverter I comes to be a high level H, and a low frequency rectangular waveform signal V1 is selected at the output terminal TD through an AND circuit 5L and an OR circuit.
