Title: Digital analog converter
Inventor: NAGASHIMA YOSHITAKE
IPC: H03M1/74
Filed: 1984-02-27
Abstract: PURPOSE:To attain low cost by adopting the capacitor switch switching system to apply weighting by an input digital value at a time region thereby decreasing number of elements. CONSTITUTION:A switch S is driven a signal in a frequency (f), and when the switch S is changed over to the position of contact (a), a capacitor C is charged up into a voltage V1, and when the switch S is changed over to the position of contact (b), the capacitor is charged to a voltage (V2-VBE). An electric charge of Q=(V2-VBE-V1).C is injected to an emitter of a transistor (TR) and a current flows to a load resistor RL. Since the electric charge is given f-times per second, the average current I is Q.f(V2-VBE-V1).f.C and a voltage of V0=RL.I is generated. The circuit is connected as shown in the figure and a frequency driving each switch S is frequency-divided by flip-flops FFn-FF0, then binary weighting is applied. Collectors of TRs are connected in a way of wired-OR and the common load resistor RL is used, and an analog output is obtained at an output terminal of an LPF.

Title: Memory circuit
Inventor: MATSUTANI YASUYUKI
IPC: G11C11/41
Filed: 1984-02-27
Abstract: PURPOSE:To accelerate both the reading speed and precharging speed by setting the precharging potential of a bit line at a high sensitivity area of a sense amplifier in case the simultaneous reading of two ports is designated to the same memory cell of a two-port RAM. CONSTITUTION:Bit lines 5 and 5' are set at the power supply voltage; while bit lines 6 and 6' are set at the ground potential respectively. Then a charge redistribution is produced between lines 5 and 6 as well as 5' and 6' when FET25-28 are turned on. In this case, the potentials of lines 5 and 6 set after the redistribution are equal to the mean value of the value at which both terminals are previously precharged and set at levels where the sensitivity of a sense amplifier is highest. The same value of potential is also obtained between lines 5' and 6'. Then the lines 5 and 6 are charged at the potential of a point (a); while lines 5' and 6' are charged at the potential of a point (b) respectively. Thus the sense amplifier can decide correctly ''1'' and ''0''.
