Title: Power amplifier
Inventor: MATSUMOTO TAKASHI
IPC: H03F1/32
Filed: 1986-12-08
Abstract: PURPOSE:To reduce the loss of power amplifier and to improve the linearity through the application of temperature compensation by adding a voltage corresponding to a threshold voltage of a power device of the power amplifier to an input signal to form a drive signal. CONSTITUTION:An input signal VIN is outputted to an adder circuit 3 as a voltage VTH corresponding to the threshold voltage VTH of the power amplifier circuit 1 by a threshold voltage generating circuit. The circuit 3 adds an output VF of a negative feedback circuit 4, the input signal VIN and the output VTH of the circuit 2 and outputs a drive voltage VDR to the amplifier circuit 1. The amplifier circuit 1 amplifies only the threshold voltage VTH or over of a power MOS FET in the voltage VDR and outputs the result to a load 5 as a transmission output voltage VOUT. The voltage VOUT enters the negative feedback circuit 4, where a negative feedback voltage VF is formed. A drain loss takes place only when the signal VIN is given and since negative feedback is applied even with the voltage VTH of the power MOSFET varied with temperature, no temperature compensation is required.

Title: Gain variable amplifier circuit and communication apparatus
Inventor: IGARASHI SADAO
IPC: H03G3/20
Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To realize performance in which distortion characteristic is excellent in the entire signal level area of a received signal. SOLUTION: A transistor T1 for amplification amplifies and outputs an inputted received signal. In such a case, the ratio of received signals to be inputted to the transistor T1 for amplification is changed by a transistor T3 for a branch in accordance with the signal level of the received signals. A transistor T5 for a bypass switches signal paths for the received signals to the transistor T1 for amplification in accordance with the signal level of the received signals. Thus, a low noise amplifier 21 realizes an amplifier circuit having an AGC function and a bypass function for signals and realizes the performance in which the distortion characteristic is superior in the entire signal level area of the received signals.

Abstract: PURPOSE:To obtain a display device driving circuit in a low cost and with low power consumption by limiting a power source circuit to one side of charge or discharge. CONSTITUTION:The voltage V0 beyond the maximum voltage of a positive gradation voltage is applied to respective data lines for a fixed period by a charging means at the time of starting the period applying the positive gradation voltage. Then, the positive gradation voltage +V3 specified by data is applied, and then, it is switched to the period applying a negative gradation voltage, and the negative gradation voltage -V3 specified by the data is applied. Thus, respective data lines are constituted so as to be applied with lower gradation voltages successively after the data lines are charged by the voltage V0 applied by the initial charging means, and the data lines follow up the applied voltages only by discharging always. Thus, respective data lines are charged by only the power source of the charging means, and the discharging are performed only by the power sources of all other gradation voltages.

Filed: 1987-11-25
Abstract: PURPOSE:To accurately control a tracking and to attain a reproducing even when one side of head is defective at the time of recording by recording a preliminary ATF pilot beforehand at the position of a regular ATF (Automatic Track Finding) pilot signal. CONSTITUTION:First, preliminary ATF pilot signals 301-305 are recorded only for the width of the track of the upper half of a position corresponding to regular ATF pilot signals 312, 322, 332, 342 and 352 to a tape 2 beforehand. At the time of recording, overwriting is executed to the signals 301-305 by a plus azimuth head (+H) or a minus azimuth head (the inverse of H) and a signal is recorded. When the +H is defective at the time of recording, for music azimuth tracks 31a, 33a and 35a, the signal is recorded with a track width and signals 302 and 304 remain between respective ones. Consequently, when the signal 331a of the track 33a is detected, next, detecting is executed in the sequence of the signals 302 and 304. Thus, even when one side head becomes defective, the reproducing can be correctly executed.
