Title:
DAC AND OSCILLATION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2018/123610
Kind Code:
A1
Abstract:
The present art relates to a Digital to Analog Converter (DAC) and an oscillation circuit capable of increasing the range of a voltage output from the DAC. A plurality of first switches are each connected to a voltage dividing resistor, and output a voltage at a point of connection between the voltage dividing resistor and the first switch, as a first voltage. A plurality of second switches are each connected to the voltage dividing resistor, and output a voltage at a point of connection between the voltage dividing resistor and the second switch, as a second voltage. The present art is applicable, for example, to a Voltage-Controlled Oscillator (VOC) for oscillating a signal of a frequency corresponding to a voltage output from a DAC.
