摘要： A sensor circuit has: a sensor portion that obtains, as an electrical signal, information on an object to be measured or detected; and a control circuit that controls the operation of the sensor portion. The control circuit receives a start input signal inputted thereto from outside for making the sensor portion operate only for a given duration after the start input signal is inputted thereto. With this configuration, it is possible to reduce the current consumption by arbitrarily controlling a period of an intermittent operation of the sensor circuit.

摘要： When the operation frequency is high, in order to cause the rate of change of outputs from an output terminal (OUT) to be abrupt, a selection control signal is caused to be in a low state, thereby causing MOS transistors (T5b, T6b) to be in ON states, thereby causing the combined resistance of the ON-resistances of the MOS resistors in a NOR gate (NOx) to be small. On the other hand, when the operation frequency is low, in order to cause the rate of change of outputs from the output terminal (OUT) to be gentle, the selection control signal is caused to be in a high state, thereby causing the MOS transistors (T5b, T6b) to be in OFF states, thereby causing the combined resistance of the ON-resistances of the MOS transistors in the NOR gate (NOx) to be large.

摘要翻译： 当操作频率高时，为了使来自输出端子（OUT）的输出的变化率突然变大，使选择控制信号处于低状态，从而使MOS晶体管（T5b，T6b） 处于导通状态，从而导致NOR门（NOx）中的MOS电阻器的导通电阻的组合电阻较小。 另一方面，当操作频率低时，为了使来自输出端子（OUT）的输出的变化率平缓，使选择控制信号处于高电平状态，从而使MOS 晶体管（T5b，T6b）处于OFF状态，从而使NOR栅极（NOx）中的MOS晶体管的导通电阻的组合电阻变大。

摘要： A magnetic sensor circuit has Hall devices 10X and 10Y, selection switch circuits 20X and 20Y, amplifier units 30X ad 30Y, a comparison unit 60, capacitors 41X, 42X, 41Y, and 42Y, and switch circuits 51 and 52. The Hall voltages obtained from the Hall devices 10X and 10Y are outputted in either of a first and a second states switched by the selection switch circuits 20X and 20Y. The amplifier units 30X ad 30Y each operate differentially and, if the difference between their outputs is greater than a set hysteresis width, the output logic of a detection signal Sdet is shifted. This configuration helps reduce the influence of device offset voltages in the Hall devices, and also helps reduce the influence of input offset voltages arising in the amplifiers.

摘要： A discrimination circuit of the present invention checks whether a received signal is noise or a signal that is repeated with interposed rest time periods, and is provided with a low-pass filter that has a cut-off frequency that is lower than the frequency of the noise but higher than the reciprocal of a total period of one frame of the signal that is repeated with interposed rest time periods and the rest time period, and a judgment circuit that judges, according to an output of the low-pass filter, whether the received signal is noise or a signal that is repeated with interposed rest time periods. With this configuration, it is possible to discriminate between noise and a signal that is repeated with interposed rest time periods, and achieve miniaturization.

摘要： In a conventional N-channel MOSFET for an open-drain circuit, when a positive static electric charge is applied to its drain, there is no route by way of which to discharge the static electric charge, resulting in a rather low static withstand voltage. To overcome this, according to the invention, an open-drain N-channel MOSFET has a drain region formed of an N-type semiconductor layer, a P-type impurity diffusion layer formed within the drain region, two high-concentration N-type impurity diffusion layers formed within the drain region so as to sandwich the P-type impurity diffusion layer, and a drain electrode connected to the P-type impurity diffusion layer and to the two high-concentration N-type impurity diffusion layers. When a positive static electric charge is applied to the drain, a parasitic transistor appears that forms a route by way of which the static electric charge is discharged.
