US6323697B1 - Low distortion sample and hold circuit - Google Patents

It is a small board cut from a 10x16cm single-sided eurocard, and is 10cm long by just over 5cm wide. Inputs and outputs are at the bottom of the board, and the power connector is at the top. This one appears to work as described by Jeurgen Haible. The 1uF capacitor in the clock circuit, is a non-polarised electrolytic. Maybe if patching it into a sequenced voltage, or using it like an arpeggiator with a keyboard controller.

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. The buffer amplifier charges or discharges the capacitor so that the voltage across the capacitor is practically equal, or proportional to, input voltage. In hold mode the switch disconnects the capacitor from the buffer.

With digital sampling comes quantization errors that create low-level noise which gets added to the reconstructed signal. The minimum analog signal amplitude that can bring about a change in the digital signal is called the Least Significant Bit LSB , while the rounding error that occurs between the analog and digital signals is referred to as quantization error. The resolution of an analog to digital converter indicating the number of discrete values it can produce over a range of analog values is typically expressed by the number of bits.

A precise sample-and-hold circuit topology in CMOS for low voltage applications with offset voltage self correction Abstract: This work describes a new topology for CMOS sample-and-hold circuits in low voltage with self-correction of the offset voltage caused by mismatches in the differential input pair of the operational amplifier. The charge injection of the NMOS switches, although not properly modeled by the simulators, is an important factor and it is minimized in this topology. Article :.

The Sampler and Zero-Order Hold models an analog sample and hold. On each clock edge, the input voltage is sampled and held until the next clock edge. The information in this topic refers to the latest Sampler and Zero-Order Hold which was introduced in version 8. In versions prior to 8.
