摘要： A transmission modulation apparatus capable of dealing with characteristic variations of a high-frequency power amplifier without always forming an amplitude loop. Transmission modulation apparatus 100 is configured with level detector 140 that receives input of a level detection control signal and detects the output signal of high-frequency power amplifier 130, and offset voltage correcting section 150 that corrects an offset voltage using collinear approximation including a first point where the relationship between the power supply voltage value and the output voltage starts to shift from linear to non-linear based on an output signal of level detector 140 and a second point where output voltage is a minimum. Offset voltage correction is adaptively executed, and linearity between the voltage value of the baseband amplitude signal and the output voltage of high-frequency power amplifier 130 when the voltage value of the baseband amplitude signal is low is compensated.

摘要： A reference voltage adjustment unit (212) calculates gain from a DA converter (121) to an offset calculating unit (123) by detecting the output of the offset calculating unit (123), adjusts the reference voltage (V3) from a reference voltage generation unit (211) so that the value becomes a predetermined value, and feeds the post-adjustment reference voltage (V4) to the DA converter (121) and offset calculating unit (123). Due to this, the gain from the DA converter (121) to the offset calculating unit (123) can be corrected. Fluctuation in the lower limit level of the output of a differential-to-single conversion unit (124) can be minimized as a result, so, the addition of unnecessary offset to the amplitude data at the amplifier unit (140) can be minimized. Thus, deterioration in modulation characteristics when the amplitude control unit (210) takes a differential circuit configuration can be minimized.

摘要： In the voltage supply circuit, a reference voltage generating circuit generates a reference voltage. An operational amplifier circuit generates an output voltage on the basis of the reference voltage. A selection circuit has at least two first terminals to select one of the first terminals and to generate a passed output voltage representing the output voltage passed through the first terminal selected. A second terminal receives the passed output voltage and is capable of outputting the passed output voltage to a load circuit. A detection circuit detects a magnitude of the passed output voltage and generates a detection voltage. The selection circuit selects a voltage corresponding to the passed output voltage generated from among at least two of the detection voltages and generates a detection voltage representing the detection voltage selected. The operational amplifier circuit decreases the difference between the reference voltage and the selected detection voltage.
