摘要： PROBLEM TO BE SOLVED: To provide a high-frequency amplifier circuit which improves a strain characteristic while keeping high-efficiency amplification even under a sharp change of an input signal level.
SOLUTION: When the amplitude V(t) (average amplitude level) of an input signal Sin(t) detected by an input level judgement circuit 22 drops to a set value Vref or lower, a signal divider 12 lowers the amplitude level of a high-frequency signal pair to be inputted into amplifiers 14-1 and 14-2 while a power supply control circuit 24 lowers the saturation output level of the amplifiers 14-1 and 14-2. Consequently, even if the amplitude V(t) of the input signal Sin(t) decreases, error signal components remaining in an output high-frequency signal Sout(t) are reduced since the amplitude level of error signals generated by the signal divider 12 is lowered.

摘要： PROBLEM TO BE SOLVED: To improve distortion characteristics for high-frequency amplifying circuits, using a simple circuit configuration.
SOLUTION: The amount of phase transitions for each of a pair of the same phase signals Sp(t)/2
0.5 in variable phase transition devices 50-1 and 50-2 is controlled so that the average electric power level of a pair of high-frequency signals S1(t) and S2(t) is equal or lower than a configured level, based on the saturation output level and the gain of amplifiers 14-1 and 14-2. The amounts of amplitude suppressed for a high-frequency output signal Sout(t) can be decreased by this control. In this method, high responsiveness is not required for the control of the amount of phase transitions for the pair of the same phase signals Sp(t)/2
0.5 , and will not lead to turning complex or rise in cost of the control circuit.

摘要： PROBLEM TO BE SOLVED: To measure a measuring target by one oscillation loop without using a frequency measuring instrument in an elastic wave sensor.
SOLUTION: The oscillation loop 20 including an oscillating elastic wave element 12 is formed. An output comb-shaped electrode 16 is formed so as to obtain characteristics that the gain characteristics between an input elastic wave level and an output electric signal level change along with a change of frequency in a pass-band. When the responsive film 18 formed on the oscillating elastic wave element 12 is adsorbed by the measuring target, the frequency of the elastic wave propagated to the output comb-shaped electrode 16 from an exciting comb-shaped electrode 12a changes and the level of the electric signal output from the output comb-shaped electrode 16 also changes. Accordingly, the concentration of the measuring target can be detected by detecting the level of the electric signal output from the output comb-shaped electrode 16.

摘要： PROBLEM TO BE SOLVED: To extract an information signal with accuracy even when a reception signal is input in a low amplitude level.
SOLUTION: By setting the ratio between the gate width Wp of a p-MOS 18 and the gate width Wn of a n-MOS 20 between 1:0.9 to 1:1.1, the capacity between the gate terminal 42 and the source terminal 22 of the p-MOS 18 is set approximately equal to the capacity between the gate terminal 44 and the source terminal 24 of the n-MOS 20. Because the component of a p-channel control signal leaked through the inter-terminal capacity between the gate terminal 42 and the source terminal 22 of the p-MOS 18 is canceled by the component of a n-channel control signal leaked through the inter-terminal capacity between the gate terminal 44 and the source terminal 24 of the n-MOS 20, it becomes possible to suppress generation of an error component in a signal output terminal 12 caused by the leak component of the two control signals.
