Non-inverting circuit. The classic non-inverting Schmitt trigger can be turned into an inverting trigger by taking V out from the emitters instead of from a Q2 collector. In this configuration, the output voltage is equal to the dynamic threshold (the shared emitter voltage) and both the output levels stay away from the supply rails.
The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...
When the inverting input is at a higher voltage than the non inverting input, the output of the comparator connects to the negative power supply. When the non inverting input is higher than the inverting input, the output is high impedance, so the output voltage in this state can be set by an external pull-up resistor to a different voltage supply.
An op amp without negative feedback (a comparator) The amplifier's differential inputs consist of a non-inverting input (+) with voltage V + and an inverting input (−) with voltage V −; ideally the op amp amplifies only the difference in voltage between the two, which is called the differential input voltage.
Schematic symbol for an OTA with differential input. Like the standard operational amplifier, it has both inverting (−) and noninverting (+) inputs; power supply lines (V+ and V−); and a single output. Unlike the traditional op-amp, it has two additional biasing inputs, I abc and I bias.
Comparators are closely related to operational amplifiers, but a comparator is designed to operate with positive feedback and with its output saturated at one power rail or the other. If necessary, an op-amp can be pressed into service as a poorly performing comparator, but its slew rate will be impaired.

Unlike the inverting amplifier, a non-inverting amplifier cannot have a gain of less than 1. A mechanical analogy is a class-2 lever, with one terminal of R 1 as the fulcrum, at ground potential. V in is at a length R 1 from the fulcrum; V out is at a length R 2 further along.
