Title: Semiconductor integrated circuit
Inventor: KANAZAWA KUNIHIKO
IPC: H01L29/80
Filed: 1984-11-10
Abstract: PURPOSE:To form a modulator and a mixer circuit with a stable action by inserting a diode between the second gate and the earth of the dual gate FET. CONSTITUTION:A signal and station transmitting signal are inputted from input terminals 1-3, and an intermediate frequency signal is removed from an output terminal 4. Here, a diode 11 inserted between input terminals 2 and 3 and an earth makes the excessive station transmitting signal input and the excessive direct current bias flow to the earth. The diode makes the excessive input flow to the earth both in the forward direction and in the reverse direction, and must leak at the pressure resistance lower than the gate pressure resistance of FET, and therefore, the diode 11 needs to obtain the shape such as a pair of two facing diodes. The diode, which satisfies these conditions, functions as a protective circuit of the mixer or the modulator. Thus, while skewness characteristics are kept satisfactorily, destruction due to an excessive input can be prevented, and the mixer and the modulator with the stable action can be realized.

Abstract: PROBLEM TO BE SOLVED: To decrease the charging frequency of a battery power source and to increase a wait time by using a photovoltaic generation means as a main power source and a battery power source as an auxiliary power source and charging the battery power source with excessive electric power of the photovoltaic generation means by an electric power control means. SOLUTION: When the electric power generated by the photovoltaic generation means 21 is large enough to drive respective system constituent elements, the power control means 19 drives the system constituent elements with the electric power generated by the photovoltaic generation means 21 through a main CPU 15. When the power control means 19 judges that the electric power generated by the photovoltaic generation means 21 is much larger than the power needed to the system constituent elements, the battery power source 17 is charged with its excessive power.  When light is not enough and the sufficient electric power is not supplied to the respective system constituent elements, the power control means 19 drives the respective system constituent elements through the CPU 15 with the electric power of the battery power source 17 and the electric power of the photovoltaic generation means 21. Consequently, the use frequency of the battery power source 17 is decreased to compensate a decrease of the electric power of the battery power source 17.
