How to compensate STC for current driven sensor?

This paper demonstrates how to determine the characteristics of ADC and silicon strain gauge when constructing a simple proportional circuit, and gives a simplified application circuit using current driven sensor. Background knowledge of silicon strain gauge The advantage of silicon strain gauge is its high sensitivity. The stress in silicon material causes the change of […]

Analysis of the solution of bandwidth mismatch in interleaved ADC

Bandwidth mismatch between interleaved ADCs should be the most difficult problem for designers. As shown in Fig. 1, the bandwidth mismatch has a gain and a phase / frequency component. This makes it more difficult to solve the bandwidth mismatch problem because it contains two components from other mismatch parameters: gain and timing mismatch. However, […]

Design of 10 bit / 400 MSPs ADC based on time interleaving Technology

By Gabriele manganaro and Dave Robertson The time interleaving technique can use multiple identical analog-to-digital converters (ADCs) and process conventional sampled data sequences at a higher sampling rate than each individual data converter. In short, time interleaving (IL) consists of time multiplexed m parallel arrays of identical ADCs, as shown in Figure 1. In this […]

What are the factors that affect the accuracy of oscilloscope measurement, and how to improve the accuracy

In the oscilloscope measurement, the problem of insufficient accuracy is common, especially in the measurement of weak small signal, phase noise, small voltage ripple, small voltage signal in large voltage. Therefore, it is particularly important for engineers to fully understand the factors that affect the accuracy of oscilloscope measurement and master its use skills before […]
