Title: Composite signal generating circuit
Inventor: MATSUBARA ATSUSHI
IPC: G09G5/00
Filed: 1989-03-10
Abstract: PURPOSE:To simplify the circuit constitution and to reduce the cost by adding a first digital signal and a second signal as they are without converting them to analog signals and generating a composite signal. CONSTITUTION:This circuit is constituted of a first input means for inputting a first digital signal Sh, a second input means for inputting a second digital signal Sv and an operational amplifier OP for adding directly a first digital signal and a second digital signal and generating a composite signal Sc. Accordingly, when a first digital signal Sh and a second digital signal Sv are inputted to the operational amplifier OP, both these digital signals are added directly as they are without converting them to analog signals and the composite signal Sc is generated. In such a way, a circuit part for converting the digital signal to the analog signal becomes unnecessary, the whole circuit constitution is simplified and the cost can be reduced.

Filed: 1981-04-21
Abstract: PURPOSE:To obtain a precise ratio between two resistors by a method wherein a pair of resistors with their conductivity type reverse to that of the substrate is formed at the central region of the substrate. CONSTITUTION:On a semiconductor substrate 1 of either conductivity type, resistor elements R1-R4 are formed with their conductivity type reverse to that of the substrate 1. Stress in the substrate 1 caused by resin sealing thereof results in a piezoresistance effect causing a change in the value of resistance. The stress, the substrate is exposed to, is the greatest at the central region and smaller toward the periphery. A change in the stress, however, is the smallest at the central region. Locating a split resistor or a plurality of resistor elements R1 and R2 with the ratio of resistance between requiring precision at the central region 23 (surrounded by a quadrangle consisting of four sides each of which divides halfways the line l extending from the center 0 to a substrate side), results in a precise ratio maintained between them.
