SampleandHoldGlieder

SampleandHoldGlieder is a term used in electronics literature to describe a modular family of sample-and-hold elements organized as discrete sections or banks. The name combines "sample and hold" with the German word Glieder meaning sections or stages, reflecting a modular construction that can be adapted to multi-channel front-ends.

A SampleandHoldGlieder stores an analog voltage sample during a hold interval, preserving the instantaneous value for subsequent processing or conversion. Each Glieder typically comprises a switching network (such as transmission gates or switches), a storage capacitor, a buffer amplifier, and a reset mechanism. A common sampling clock may drive multiple Glieder to enable synchronized sampling across channels, enabling parallel or multiplexed acquisition without requiring a dedicated ADC for every channel.

In typical bank architectures, Glieder operate in a staggered or multiplexed fashion, allowing high-channel-count acquisition with controlled timing while keeping the analog front-end compact. Design trade-offs include capacitor size, switch leakage, charge injection, and aperture jitter, all of which influence voltage accuracy, droop during the hold interval, and overall performance.

Applications for SHG concepts include data acquisition systems, multiplexed front-ends for ADCs, and precision instrumentation where multiple analog signals must be sampled with defined timing relationships. Variants may differ in switch technology (CMOS transmission gates or other), capacitor topology, and clocking schemes (single-ended or differential).

Terminology around SampleandHoldGlieder is not widely standardized and is primarily found in niche or German-language texts. When encountered, it is advisable to consult the specific schematic and datasheet to understand the exact topology and performance characteristics.
