A High Speed Family of Commercial Track-and-Hold Devices for
The IC shown in Fig. It features an adjustable track period length controlled by the t2crl voltage that modifies the states of internal delay lines. This allows for maximizing the length of the valid output step. The differential gain of the chip is approximately 0 dB , which corresponds to a single-ended-to-differential gain of -6 dB. The gain can be adjusted using the external control voltage gain cnrl. The chip supports both AC-coupled and DC-coupled inputs. In the DC-coupled mode, the input common-mode voltage must be equal to vcc for optimal performance of the chip.
The input sampled data path includes an equalizer that increases the bandwidth of the chip. The level of equalization is controlled by the external voltage varcrl.
The frequency response and gain of ASNT is also controlled by the positive supply voltage vp0p9 that powers the input buffers of the Track-and-Hold. This voltage defines the common mode of the data signal at the input of the sampling switch and thus the frequency response of the device. Lower voltages result in less peaking in the input buffer and less overall gain of the device.
The differential DC signaling mode is recommended for optimal performance. More than 8-bit accuracy within the full frequency range. Sampling speed from 50MSps to 4GSps. Nominal 0dB differential gain with manual adjustment. Adjustable duty cycle of the internal sampling clocks. Adjustable input bandwidth. Adjustable overall gain.

US4390844A - Integration filter for step waveforms - Google Patents
Year of fee payment : 4. Year of fee payment : 8. Effective date : A method and apparatus for converting an input step waveform signal into a smooth output waveform signal is comprised of two sample-and-hold circuits 11, 12 , one for sampling each step of the input signal and the other for synchronously sampling and holding the output waveform, a circuit for providing a signal proportonal to the difference between the samples held in the sample-and-hold circuits, and means for integrating the difference. The output of the integrator is connected to the second sample-and-hold circuit while the step waveform to be filtered is connected to the input of the first sample-and-hold circuit. The integrator thus produces an output that is a linear signal during each clock pulse period with a slope equal the sign and amplitude of each step.
A high-speed sample-and-hold circuit based on CMOS transmission lines
Definition: The Sample and Hold circui t is an electronic circuit which creates the samples of voltage given to it as input, and after that, it holds these samples for the definite time. The time during which sample and hold circuit generates the sample of the input signal is called sampling time. Similarly, the time duration of the circuit during which it holds the sampled value is called holding time. It will not be wrong to say that capacitor is the heart of sample and hold circuit. This is because the capacitor present in it charges to its peak value when the switch is opened, i.
US3696305A - High speed high accuracy sample and hold circuit - Google Patents
In electronics , a sample and hold also known as sample and follow circuit is an analog device that samples captures, takes the voltage of a continuously varying analog signal and holds locks, freezes its value at a constant level for a specified minimum period of time. Sample and hold circuits and related peak detectors are the elementary analog memory devices. They are typically used in analog-to-digital converters to eliminate variations in input signal that can corrupt the conversion process. A typical sample and hold circuit stores electric charge in a capacitor and contains at least one switching device such as a FET field effect transistor switch and normally one operational amplifier.

Effective date : Year of fee payment : 4. Year of fee payment : 8. Year of fee payment : Disclosed is an analog to digital conversion system that converts high speed analog signals to digital values without using a hold circuit. The system has a narrow aperture sampling circuit that samples an input signal and feeds the sampled signal to a capacitor.

You have hit the spot. There is something in this and the idea is good, I support it.
Quite right! The idea is good, I agree with you.
It's just an excellent idea
