In the last tutorial, we learned about counter-type ADCs, which are single slope ADCs with an incrementing slope. Further, the counter value only increments until it matches the analog input voltage value. In simple words, the counter resets to zero after every single conversion. The counter counts only upward. Hence, it has only a positive … Read more
The counter type analog-to-digital converter is a simple ADC, also known as a staircase or ramp analog-to-digital converter. As its name suggests, it uses a binary counter for the conversion of analog signals. The schematic consists of a comparator, counter, digital-to-analog converter, a control circuit, an AND gate, and output latches. The article provides an … Read more
In this tutorial, we will discuss slope-type or integration-type ADCs. In the last tutorial, we discussed successive approximation and flash-type ADC. There are two types of slope ADCs: single slope and dual slope. Firstly, we will discuss single slope, and after that, we will see the workings of dual-slope integration ADC. Recommended Books Books that … Read more
In this tutorial, we will discuss the workings of a flash ADC. A flash ADC, or flash analog-to-digital converter, is the fastest type of ADC among all the other ADCs. It is also known as a parallel analog-to-digital converter. It comprises high-speed comparators, resistive voltage divider circuits, and a priority encoder. The tutorial is a … Read more
In this tutorial, we will talk about successive approximation ADC. This type of ADC converts an analog signal into a digital signal using a binary search through all possible quantization levels. Firstly, we will discuss what ADC is. After that, we will discuss the introduction, working, example circuits, advantages, and disadvantages of successive approximation ADC. … Read more
The binary-weighted DAC is appropriate for DACs with low resolving power. This is because it requires a wide range of precise resistors to perform error-free operations for high-order DACs. It is impossible to maintain the accuracy of the weighted DACs and is expensive. This leads to the R-2R ladder technique, which implements only two resistors … Read more
In this tutorial, we will discuss the workings of a binary-weighted resistor DAC. It consists of an inverting amplifier op-amp and a string of weighted resistors to distinguish each bit starting from the LSB to the MSB position. Each resistor represents a digital bit to be converted into analog form. The maximum amount of information … Read more
A transistor is an electronic component that is also used as a digital switch. It works similarly to a mechanical switch, but it is controlled by a digital high logic signal instead of traditional push buttons. Traditional switches are manually controlled by applying mechanical force. Recommended Books Books that cover this topic in more depth. … Read more
Zero crossing detection circuit comprises two main electronics components. One is an operational amplifier and the second one is passive electronic components such as resistors, capacitors. It detects a zero voltage reference point of the AC signal or a sine wave that is a zero crossing point of the AC signal. The operational amplifier (Op-amp) … Read more
