FAQ about Linear - Comparators

1. What is a logic level comparator?
A logic level comparator is an electronic device that compares the magnitude of two voltage signals and outputs a corresponding high or low level according to the comparison result. Comparators are usually used in applications such as digitization of analog signals, voltage comparison and triggering.
Working Principle
A comparator is usually composed of a differential amplifier with two input terminals (positive input terminal and negative input terminal) and an output terminal. When the voltage at the positive input is higher than that at the negative input, the output voltage is high; when the voltage at the negative input is higher than that at the positive input, the output voltage is low. When the voltages at the two inputs are equal, the output voltage depends on the characteristics of the comparator. There may be a certain offset voltage, or the output is in an uncertain state. -
2. What are the most common comparators?
The most common types of comparators include zero-level comparators (zero-crossing comparators), arbitrary-level comparators (captured-zero comparators), and hysteresis comparators (Schmitt triggers).
Zero-level comparator (zero-crossing comparator)
The reference voltage of the zero-level comparator (zero-crossing comparator) is zero. When the input voltage crosses the threshold voltage, the output voltage jumps. This type of comparator can be divided into two types: inverting input and non-inverting input according to the different input methods. Its transfer characteristics are drawn by finding the threshold and analyzing the output voltage change law when the input voltage changes from the lowest to the highest and from the highest to the lowest.

3. What is the most common comparator?
The most common types of comparators include zero-level comparators (zero-crossing comparators), arbitrary level comparators (captured zero comparators), and hysteresis comparators (Schmitt triggers).
Zero-level comparator (zero-crossing comparator)
A zero-level comparator is a circuit that compares an analog input signal with a fixed reference voltage (threshold voltage). When the input voltage crosses the threshold voltage, the output level changes. This comparator is usually used to detect whether the signal is zero or exceeds a certain threshold. According to the different input methods, it can be divided into two types: inverting input and non-inverting input.
Arbitrary level comparator (captured zero comparator)
The arbitrary level comparator is to change the ground terminal in the zero level comparator to a reference voltage (UR). By adjusting the size and polarity of the reference voltage, different threshold voltages can be set. This comparator has a simple structure and high sensitivity, but poor anti-interference ability, and is suitable for application scenarios that require high sensitivity.
Hysteresis comparator (Schmitt trigger)
The hysteresis comparator is also called a Schmitt trigger or hysteresis comparator, which has two different threshold voltages, corresponding to the input signal from large to small and from small to large. The output voltage of this comparator will produce a "hysteresis" phenomenon when the input signal approaches the threshold, thereby preventing the output state from repeatedly jumping near the threshold. Hysteresis comparators are also divided into two types: inverting input and non-inverting input.
