Can someone explain how this transistor comparator works?
Apr 10, 2015 · Knowing what you are actually wanting and trying to do would help immensely in answering your questions and providing a solution that suits. It's a real comparator. Analog comparators are linear devices optimised to make use of the high available gain.
single transistor as a comparator?? : r/AskElectronics - Reddit
Oct 3, 2022 · they are probably assuming an "ideal" transistor with infinite gain, stable Vbe turn on/off, and so on. NOBODY would actually do a comparator this way, but you probably could get it to kind of work in a lab
Suppose parameter P of two rectangular devices has a mismatch error of ΔP. The variance of parameter ΔP b/t the two devices is. Ref: M. J. M. Pelgrom, et al., “Matching properties of MOS transistors,” IEEE Journal of Solid-State Circuits, vol. 24, pp. 1433-1439, issue 5, 1989. ... PMOS diode pull up : Resistor pull up :
After operational amplifiers (op amps), comparators are the most generally used analog, simple integrated circuits. Operational amplifiers are well described in many publications and a lot of information can be found regarding the design and proper use of these devices.

May 22, 2022 · A high on the base will turn on the transistor, thus placing the LM311's output at a logic high. Figure \(\PageIndex{9}\): LM311 with strobe. Our final type of comparator circuit is the window comparator. The window comparator is used to determine if a particular signal is within an allowable range of levels.
Analog to digital converters are critical components for digital world of signal processing systems as communication systems. A comparator is a sub-circuit of the analog to digital converters which is responsible of comparing two given voltage values, and give a binary logic decision.

Transistor Comparator. The basic differential amplifier circuit using bipolar transistor shown in Figure 3 acts as a voltage comparator circuit, where V o (t) is the input signal to be compared with a reference voltage V. For good results, it is necessary that the transistors Q 1 and Q 2 as will as resistors RC 1 and RC 2 are well matched.

However at their heart, the basic concept of a comparator is a differential amplifier but with an output that swings between two states. For this project, I’m going back to basics and attempting to implement a comparator with discrete transistors.
Comparator - Wikipedia
High speed comparators use transistors with larger aspect ratios and hence also consume more power. [6] Depending on the application, select either a comparator with high speed or one that saves power.
What is a Comparator? The comparator is a circuit that compares one analog signal with another analog signal or a reference voltage and outputs a binary signal based on the comparison. The comparator is basically a 1-bit analog-to-digital converter: Comparator symbol: 060808-01 1-Bit Quantizer 1-Bit Encoder Reference Voltage Analog Input 1-Bit ...
