摘要： A transmission circuit precisely compensates for an offset characteristic of an amplitude modulation section and operates with low distortion and high efficiency over a wide output power range. A signal generation section outputs an amplitude signal and an angle-modulated signal. An amplitude amplifying section supplies, to the amplitude modulation section, a voltage corresponding to a magnitude of an inputted amplitude signal. The amplitude modulation section amplitude-modulates the angle-modulated signal by the voltage supplied from the amplitude amplifying section, thereby outputting a resultant signal as a modulation signal. A temperature measuring section measures a temperature of the amplitude modulation section. An offset compensation section calculates an offset compensation value in accordance with a change, in temperature of the amplitude modulation section, from the temperature of the amplitude modulation section in an initial state, and adds the calculated offset compensation value to the amplitude signal.

摘要： Provided is a frequency modulation circuit 1 for outputting a highly precise frequency-modulated signal regardless of variation in a characteristic of a VCO 15. A correction value calculation section 17 calculates a correction value Vt2 based on a voltage value (Vtx−Vt1) resulting from subtracting a control voltage Vt1, which is generated by a control voltage generation section 11, from a control voltage Vtx at which a sensitivity of the VCO 15 is maximized. A variable amplifier 18 amplifies the correction value Vt2. An addition section 13 outputs a control voltage Vt3, which results from adding the amplified correction value Vt2 to the control voltage Vt1, to the VCO 15 via a DAC 14.

摘要： A receiving device includes a receiver circuit for outputting a received signal as a reception electric field intensity signal, an operation control circuit for controlling an operation of the receiver circuit, and an intermittent reception control circuit for outputting a periodic signal. A comparator circuit holds a first threshold indicating that the receiving device has entered a communication area and a second threshold indicating a start of a continuous electric field intensity measurement. If the reception electric field intensity signal is lower than the second threshold, the operation control circuit makes the receiver circuit perform intermittent operation. If the reception electric field intensity signal is equal to or higher than the second threshold, the operation control circuit makes the receiver circuit perform a continuous operation. If the reception electric field intensity signal is equal to or higher than the first threshold, the operation control circuit makes the demodulation circuit perform an operation.
