Title: Circuit for correcting gain of portable telephone set
Inventor: O TAIRA
IPC: H04B1/40
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To make it unnecessary to operate temperature correction by a temperature sensor, or the correction processing of reception radio wave intensity value in a base band IC by transmitting a signal through an attenuator using a thermister in a transmitting/receiving circuit, and correcting gain fluctuation due to the change of the characteristics of a circuit element due to temperature change. SOLUTION: In an RF transmitting/receiving circuit 5 of a portable telephone set, an π type attenuator constituted of resistance R1-R3 and a thermister TH is inserted between a mixer 25 and a band pass filter 24, and a temperature sensor IC is removed. When the temperature of the thermister TH of the π, type attenuator is increased, a resistance value is decreased, the attenuating amounts of the π, type attenuator are increased, and the gain of the whole circuit is decreased. When the temperature of the thermister TH is decreased, the resistance value is increased, the attenuating amounts of the π type attenutor are decreased, and the gain of the whole circuit is increased. Thus, the gain changing amounts due to the temperature change of the whole circuit can be corrected, and the gain of the whole RF receiving circuit can be always made constant. Therefore, it is not necessary to operate the correction processing of a reception radio wave intensity value in the base band IC.

Title: Phase locking circuit
Inventor: SAKAMOTO TOSHIYUKI
IPC: H04N19/00
Filed: 1985-04-19
Abstract: PURPOSE:To reproduce the synchronizing and system clocks with high stability and high accuracy by controlling a clock generator with the output of an A/D converter. CONSTITUTION:The phase error signal 6 having the information on the phase advance and delay obtained by a sample and hold circuit 5 is applied to a D/A converter 7. A voltage control oscillator VCO 9 changes its oscillation frequency according to the output voltage 8 of the converter 7 and supplies an oscillation output pulse train 10 of its own to an A/D converter 2 in the form of clocks for control of the sampling phase. Therefore the horizontal synchronizing pulse of the output of the converter 2 is phase locked to the train 10. Thus it is possible to reproduce the clock synchronous with the sampling phase of the transmission side with high stability and high accuracy.
