ABSTRACT:
An FM receiver capable of generating a signal showing the electric field intensity of a received signal. More particularly, an FM receiver capable of generating a signal showing the electric field, wherein the dynamic range is expanded, and the linearity is improved. The enlargement of the dynamic range of the signal showing the electric field intensity may be effected, and also the linearity may be improved. Accordingly, the electric field intensity of the received signal may be correctly displayed by a display, etc. Especially, as the gain control is effected through the control of the operation current of the gain control amplification circuit in accordance with the gain control signal by the differential type of level detection circuit, an FM receiver suitable for IC may be provided.
