DAC AND OSCILLATION CIRCUIT

The present technology relates to a DAC (Digital to Analog Converter) and an oscillation circuit that allow widening of a range of a voltage to be output from the DAC. A plurality of first switches is connected to a voltage-dividing resistor and each configured to output, as a first voltage, a volta...

Zusammenfassung:	The present technology relates to a DAC (Digital to Analog Converter) and an oscillation circuit that allow widening of a range of a voltage to be output from the DAC. A plurality of first switches is connected to a voltage-dividing resistor and each configured to output, as a first voltage, a voltage at a corresponding one of connection points between the voltage-dividing resistor and the plurality of first switches. A plurality of second switches is connected to the voltage-dividing resistor and each configured to output, as a second voltage, a voltage at a corresponding one of connection points between the voltage-dividing resistor and the plurality of second switches. The present technology can be applied to, for example, a VCO (Voltage-Controlled Oscillator) and the like that oscillates a signal with a frequency according to a voltage to be output from a DAC.
