IPC: G06F7/506
Filed: 1985-09-24
Abstract: PURPOSE:To decrease the number of gates together with reduction of the power consumption and to increase the arithmetic speed, by using a carry transmission circuit consisting of two switch means. CONSTITUTION:When input terminals AK and BK have different logic levels of input value, the output OK of an exclusive OR gate 1 is equal to logic '1' with a switch N1 turned on. Then the carry given from the bit K-1 of a carry input terminal CK-1 is sent as it is to a carry output terminal CK. While a NOT gate 3 has its output equal to logic '1' when the logic levels of input value are equal to each other between both terminals AK and BK. Then a switch N2 is turned on and the input value of the terminal AK is sent to a carry output terminal CK. Thus the number of gates is decreased together with reduction of the power consumption and also the arithmetic speed is increased with addition of such a carry transmission circuit.

Title: Signal polarity switching circuit
Inventor: FUJITA HIROSHI
IPC: G02F1/133
Filed: 1990-08-10
Abstract: PURPOSE:To prevent a large difference from occurring in the phase characteristic of a current signal even when the frequency band of an input voltage signal is equal to or exceeds several MHz by alternately outputting the in-phase output and the reverse phase output of a differential amplifier circuit to a current/ voltage conversion circuit in the case of positive polarity and in the case of negative polarity. CONSTITUTION:A video signal(input voltage signal) alpha outputted from a video processing circuit is guided to the differential amplifier circuit 10 through an input terminal. When the input voltage signal alpha is changed, two parallel outputs outputted from the circuit 10 as the current signal according to the change of the signal alpha, that means, the in-phase output and the reverse phase output are changed. Furthermore, the in-phase output and the reverse phase output from the circuit 10 are alternately guided by a polarity switching circuit 20 to the current/voltage exchange circuit 30, where they are converted into voltage. Thus, the signal polarity switching circuit in which the phase characteristic is not deteriorated even in the frequency band which is equal to or exceeds several MHz is obtained.
