  • Patent number: 11508686
    Abstract: A semiconductor device includes a semiconductor chip and a package. The semiconductor chip includes a signal processing circuit, a plurality of pads, and a first resistor which arc formed on a semiconductor substrate. On the semiconductor chip, there is no shot-circuiting between a first pad and a second pad of the plurality of pads. A signal input terminal of the signal processing circuit is connected to the second pad. The first resistor is provided between a reference potential supply terminal for supplying a power supply potential and the first pad. A specific terminal of the plurality of terminals of the package is connected to the first pad by a first bonding wire, and is connected to the second pad by a second bonding wire.

  • Patent number: 11228286
    Abstract: A linear amplifier outputs differential signals corresponding to differential signals input to a first signal input terminal and a second signal input terminal, and includes a first resistor, a second resistor, a third resistor, a fourth resistor, a first capacitor, a second capacitor, a third transistor, a fourth transistor, a differential amplifier, and a signal processing circuit. The signal processing circuit includes a first transistor and a second transistor, and includes a resistor as a common voltage output part that outputs a common voltage. The differential amplifier receives the common voltage and a reference voltage, and applies a voltage corresponding to the voltage difference between the common voltage and the reference voltage to the control terminals of the transistors.

  • Patent number: 9337729
    Abstract: The DC-DC converter includes a reference voltage generating circuit that generates a reference voltage. The DC-DC converter includes a modulation clock signal generating circuit that generates a modulation clock signal. The DC-DC converter includes a modulator that performs modulation of the reference voltage in synchronization with the modulation clock signal and outputs a resulting reference signal. The DC-DC converter includes a first comparator that compares the reference signal and a first feedback signal, which is based on the output voltage, and outputs a signal based on a result of the comparison. The DC-DC converter includes a driver that shapes a waveform of a PWM signal, which is based on the signal output from the first comparator, and outputs the PWM signal with the shaped waveform to the control node.
