Filed: 1980-08-12
Abstract: PURPOSE:To suppress the malfunction at the application of power supply with steep rise, by connecting the emitter and the collector of a PNP transistor between the emitter and the base of the PNP transistor objective to the prevention of malfunction. CONSTITUTION:A collector of a malfunction preventing PNP transistor (TR)Q1 is connected to a base of a PNP TRQ2 being the objective of malfunction and the emitter is connected to a power supply VCC. When a power supply voltage steep in rise is applied, a charging current flows to a parasitic capacitor C1 of the TRQ1 through the emitter and the base. Thus, a current hFE times the charging current of the parasitic capacitor C1 flows to the collector of the TRQ1, and this flows in a parasitic capacitor C2 of the TRQ2 as a charging current, and the current flowing to the capacitor C2 via the emitter and the base of the TRQ2 is very less and only small output current I' is caused.

Title: Frequency modulating circuit
Inventor: TAROUMARU MAKOTO
IPC: H03C3/00
Filed: 1993-05-13
Abstract: PURPOSE:To provide an excellent frequency modulating circuit in a simple constitution where a compensating circuit applying a filter is added to a conventional PLL and by obtaining the modulation sensitivity characteristic that is flat up to a low band against the modulated signal frequency. CONSTITUTION:A frequency modulating circuit works in the exactly same way as a conventional PLL circuit when a compensating circuit 6 is not used and therefore has the frequency characteristic of the modulation sensitivity having its peak with the frequency fp approximate to the PLL gain crossing frequency. Meanwhile the circuit 6 functions as an HPF and therefore has an attenuated variable equal to the increased variable of sensitivity with the frequency fp set at the peak of the frequency characteristic of the modulation sensitivity. As a result, the modulated signal that passed through the circuit 6 has its suppressed low band. In other words, the frequency characteristic can be previously given to the modulated signal so that the increased variable of sensitivity is offset at the peak of the modulation sensitivity. Thus it is possible to suppress the peak in a low band of the modulation sensitivity and to improve the modulation characteristic by giving such frequency characteristic to the modulated signal.
