Abstract: PURPOSE:To reduce the power consumption of a boot-strap circuit and to realize the high degree of integration by performing a specific circuit forming of the said circuit of a timing generating circuit. CONSTITUTION:In a pseudo static type RAM constituted of dynamic type memory cells, its boot-strap circuit that generates a timing signal higher than the power supply voltage VCC consists of a P-type FET Q60, an N-type FET Q61 in series with the former, a CMOS inverter that receives a boot-strap start-up signal phibm, an N-type FET Q64 which the Q61 is connected with and its gate is connected with the power source, an N-type one Q62 of which gate is connected with the power source, and an N-type one Q63 in series with the former. The FETs Q60 and Q61, and those Q62 and Q63 are both formed as CMOS, and hence only either one of the CMOS is turned on. And the charge/discharge of a boot-strap capacitor CB is controlled by one of the said FETs. A through- current is prevented from occurring by the effect of the said complementary on-state of the FETs in CMOS constitution, and therefore, the power consumption is reduced. Also, the conductance characteristics of the FETs can be made irreducible because of their drive current forming, and accordingly, the circuit integration is upgraded.

IPC: H04B10/07
Filed: 1980-05-08
Abstract: PURPOSE:To increase the reliability for a transmission of digital signals, by transmitting the positive and negative pulses of a bipolar signal after modulating said pules into the optical signals of separate wavelengths. CONSTITUTION:A bipolar signal itself is easily checked for its error with a high reliability, and only a unipolar signal is acceptable for an optical transmission. In this connection, the bipolar signal is divided through a separating circuit 11 into a positive pole signal and a negative pole signal. The unipolar signal of positive pole is converted into an optical signal of wavelength lambda1 by a modulating circuit 13; and the unipolar signal of negative pole is converted into an optical signal of wavelength lambda2 by a modulating circuit 14. These optical signals are synthesized through an optical synthesizing circuit 15 and then transmitted. At the reception side the input optical signal is divided into two optical signals of wavelengths lambda1 and lambda2 and synthesized after conversion into the electric signals. In such a way, a bipolar signal is obtained.
