| 20130241622 | RECEIVER WITH TIME-VARYING THRESHOLD VOLTAGE - A system for communicating information between circuits is described. A transmit circuit provides pulse-amplitude-modulation (PAM) signals via a communication channel to a receiver. A circuit in the receiver determines digital values from the received signals using a time-varying threshold voltage, which varies during the bit-time. This approach may compensate for inter-symbol interference (ISI) to increase the voltage and timing margins of the system. | 09-19-2013 |
| 20140035651 | Sensor Circuit for Detecting the Setting of an Integrated Circuit - Methods and apparatus selecting settings for circuits according to various aspects of the present invention may operate in conjunction with a measurement element connected to the circuit. The circuit may include a voltage source adapted to supply a voltage to the measurement element. The voltage may be substantially independent of the characteristics of the measurement element. The circuit may further include a measurement sensor responsive to a current in the measurement element. The measurement sensor may generate a control signal according to the current in the measurement element. | 02-06-2014 |
| 20140084983 | SEMICONDUCTOR DEVICE - The present invention is directed to prevent occurrence of a problem on a withstand voltage in a circuit group which receives supply of an internal power supply voltage. An error amplifier outputs a control voltage obtained by amplifying a difference voltage between a reference voltage and a divided voltage obtained by dividing an internal power supply voltage to an output node. A drive transistor supplies a drive current according to the control voltage of the output node of the error amplifier from an external power supply line to an internal power supply line. When the divided voltage exceeds a predetermined voltage, a clamp circuit changes the control voltage in the direction of decreasing the drive current. | 03-27-2014 |
