Analog-to-digital converter. In electronics, an analog-to-digital converter ( ADC, A/D, or A-to-D) is a system that converts an analog signal, such as a sound picked up by a microphone or light entering a digital camera, into a digital signal.
In electronics, a digital-to-analog converter ( DAC, D/A, D2A, or D-to-A) is a system that converts a digital signal into an analog signal. An analog-to-digital converter (ADC) performs the reverse function. There are several DAC architectures; the suitability of a DAC for a particular application is determined by figures of merit including ...
Integrating ADC. An integrating ADC is a type of analog-to-digital converter that converts an unknown input voltage into a digital representation through the use of an integrator. In its basic implementation, the dual-slope converter, the unknown input voltage is applied to the input of the integrator and allowed to ramp for a fixed time period ...
The successive-approximation analog-to-digital converter circuit typically consists of four chief subcircuits: A sample-and-hold circuit to acquire the input voltage V in. An analog voltage comparator that compares V in to the output of the internal DAC and outputs the result of the comparison to the successive-approximation register (SAR).
Resistor ladder. A resistor ladder is an electrical circuit made from repeating units of resistors, in specific configurations. An R–2R ladder configuration is a simple and inexpensive way to perform digital-to-analog conversion (DAC), using repetitive arrangements of precise resistor networks in a ladder -like configuration.
In electronic instrumentation and signal processing, a time-to-digital converter ( TDC) is a device for recognizing events and providing a digital representation of the time they occurred. For example, a TDC might output the time of arrival for each incoming pulse. Some applications wish to measure the time interval between two events rather ...
Overview. Integrated circuits (ICs) are generally classified as digital (e.g. a microprocessor) or analog (e.g. an operational amplifier ). Mixed-signal ICs contain both digital and analog circuitry on the same chip, and sometimes embedded software. Mixed-signal ICs process both analog and digital signals together.
The time-stretch analog-to-digital converter ( TS-ADC ), [1] [2] [3] also known as the time-stretch enhanced recorder ( TiSER ), is an analog-to-digital converter (ADC) system that has the capability of digitizing very high bandwidth signals that cannot be captured by conventional electronic ADCs. [4] Alternatively, it is also known as the ...
