20110234441 | CYCLIC A/D CONVERTER - A control circuit connects a capacitor to an input terminal and an output terminal of an operational amplifier and applies a signal charge to charge the capacitor with a switch being turned off. Thus, a conversion voltage corresponding to the signal charge is outputted from the operational amplifier. The control circuit then sets charges, which correspond to the conversion voltage, in capacitors and reallocates the charges among the capacitors by connecting non-common electrodes of the capacitors to either one of a plurality of reference voltage lines in accordance with a conversion result of an A/D conversion circuit with the capacitor being connected to the input terminal and the output terminal of the operational amplifier. The control circuit thereafter performs, a number of times, charge setting, initialization and subsequent charge reallocation in accordance with a residual voltage outputted from the operational amplifier. | 09-29-2011 |

The amplifier circuit is provided with a single end output configuration and differentially amplifies input voltages inputted to input terminals and outputs an imbalanced signal from a second output terminal. When the first and fourth switches are turned on and the second switch is turned off, the load circuit functions as a load on the differential pair and the first output terminal is internally connected. The amplifier circuit is provided with a differential output configuration and differentially amplifies the input voltages inputted to the input terminals and outputs balanced signals from the output terminals. | 10-06-2011 |
20130207687 | LOGIC SIGNAL TRANSMISSION CIRCUIT WITH ISOLATION BARRIER - A logic signal transmission circuit includes a driving circuit, an isolation section, and a latch section. The driving circuit converts an input digital signal to a differential digital signal. The isolation section blocks direct current and passes the differential digital signal. The latch section has even numbers of inverters which are connected in a loop and output a logic signal by turning ON and OFF a power supply voltage in a complementary manner. An input impedance of the latch section is set so that when a logic level of the differential digital signal changes, a transient voltage inputted through the isolation section to the latch section changes across a threshold voltage of the latch section. When the transient voltage changes across the threshold voltage, a logic level of the logic signal changes. | 08-15-2013 |
20140176148 | VOLTAGE DETECTING DEVICE FOR ASSEMBLED BATTERY - In a voltage detecting device, a control unit turns on first switches and fifth switches corresponding to a plurality of unit batteries of an assembled battery to charge electric charge to first capacitors. The control unit simultaneously turns off at least one of the first switches or the fifth switches to hold the electric charge in the first capacitors. While selecting one of the unit batteries in a predetermined order as a target unit battery for voltage detection, the control unit temporarily turns off a fourth switch to reset electric charge of a second capacitor, and then turns of second switches and third switches in a state where one of the first switches and one of the fifth switches corresponding to the target unit battery are kept in an off state, thereby to detect a voltage of the target unit battery. | 06-26-2014 |
