DIGITAL-TO-ANALOG SIGNAL CONVERTER AND IMAGE SENSOR INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17986966 titled 'DIGITAL-TO-ANALOG SIGNAL CONVERTER AND IMAGE SENSOR INCLUDING THE SAME
Simplified Explanation
The abstract describes a digital-to-analog converter (DAC) that converts digital signals into analog voltages. The DAC includes a first channel that outputs a ramp voltage and a first bias circuit that applies a bias voltage to the first channel. The first channel consists of multiple current cells, selection circuits, switches, and a resistor connected to the output node. The selection circuits connect the current cells to the resistor and switches based on digital input signals.

Original Abstract Submitted
A digital-to-analog converter includes a first channel configured to output a first ramp voltage through an output node, and a first bias circuit configured to apply a bias voltage to the first channel. The first channel comprises a plurality of current cells connected to the first bias circuit, a plurality of selection circuits and a plurality of switches, and a first resistor connected to the output node. Each of the plurality of selection circuits of the first channel comprises a first selection circuit configured to connect a current of one of the plurality of current cells to the first resistor in accordance with a first digital input signal, and a second selection circuit configured to connect the current of the current cell to one of the plurality of switches corresponding to the current cell in accordance with a second digital input signal complementary to the first digital input signal.
