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]
Time interleaved (TI) ADCs are Analog-to-Digital Converters (ADCs) that involve M converters working in parallel. [1] Each of the M converters is referred to as sub-ADC, channel or slice in the literature. The time interleaving technique, akin to multithreading in computing, involves using multiple converters in parallel to sample the input ...
The Wilkinson ADC was designed by Denys Wilkinson in 1950. The Wilkinson ADC is based on the comparison of an input voltage with that produced by a charging capacitor. The capacitor is allowed to charge until a comparator determines it matches the input voltage. Then, the capacitor is discharged linearly by using a constant current source. The ...
The voltage on the capacitor v is directly proportional to the time interval T and can be measured with an analog-to-digital converter (ADC). The resolution of such a system is in the range of 1 to 10 ps. [12] Although a separate ADC can be used, the ADC step is often integrated into the interpolator.
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 run-up period).
Counter type ADC: The D to A converter can be easily turned around to provide the inverse function A to D conversion. The principle is to adjust the DAC's input code until the DAC's output comes within ± 1 ⁄ 2 LSB to the analog input which is to be converted to binary digital form. Servo tracking ADC: It is an improved version of a counting ...
ADC earnings call for the period ending December 31, 2024. ... And I would note that the noncash G&A is really the driver of that is the function of going from a five-year restricted time-based ...
Note: many sources [11] §6.1 [26] [27] also analyze a ΔΣ ADC's modulation loop in the z-domain, which implicitly treats the continuous analog input as a discrete-time signal. This may be a valid approximation provided that the input signal is already bandlimited and can be assumed to be not changing on time scales higher than the sampling rate.
