Types, principles, application characteristics and Simulation of multivibrator

introduction Multivibrator is often used in digital system circuits. Multivibrator is a self-excited oscillator. After the power is turned on, it can generate a rectangular wave with a certain frequency and width without adding a trigger signal. This output waveform is used as the clock signal source in the circuit. Because the rectangular wave contains […]

Based on TSMC 0.25 μ Design of ADC sample and hold circuit based on M CMOS process

introduction In recent years, with the rapid development of digital signal processing technology, digital signal processing technology is widely used in various fields. Therefore, as a bridge between analog and digital systems, the performance of analog-to-digital converter (ADC) is also put forward higher and higher requirements. Low voltage high-speed ADC is a key part in […]

Research on new DPGA device based on divergence exponential curve

DPGA (digital programmable gain amplifier) is a practical signal processing element, which is applied when analog-to-digital converter must obtain signals in a wide dynamic range. If the input signal amplitude cannot be accommodated to match and effectively utilize the analog-to-digital converter span, the low input may not be digitized with sufficient resolution, and the high […]

Basic logic operation and its circuit implementation

Experimental principle In logical algebra, there are three basic logical operations: and, or and not. As shown in Figure 1, the control circuit of three indicator lights is given. In the circuit of Fig. 1 (a), the indicator light will be on only when two switches are closed at the same time. This causal relationship […]

Application characteristics and advantage analysis of Ti 32-bit incremental cumulative analog-to-digital converter

Review: Recently, Texas Instruments (TI) launched a pair of 32-bit incremental cumulative analog-to-digital converters (ADCs). These two devices combine high resolution, low noise and integrated fault detection, which successfully solved the problem that the required performance and characteristics could not be obtained in the past when evaluating and selecting devices. In addition, ads1262 and ads1263 […]
