Today, Inline Closure manufacturers share what is an active device:

1. If an electronic component has a power supply inside it, the device is called an active device.

Second, from the nature of the circuit, active devices have two basic characteristics:

1. It also consumes electricity.
2. In addition to the input signal, there must be an external power supply to work properly.

Third, active devices are the main components of electronic circuits. From physical structure, circuit functions and engineering parameters, active devices can be divided into two categories: discrete devices and integrated circuits.

1. Discrete devices: bipolar transistor, field effect transistor, thyristor, semiconductor resistor and capacitor.

2. Analog integrated circuit devices: integrated operational amplifiers, comparators, logarithmic and exponential amplifiers, analog multipliers/dividers, analog switching circuits, phase lock loops, integrated voltage regulators, reference power supplies, waveform generators, Power amplifier.

3. Digital integrated circuit devices: basic logic gates, flip-flops, registers, decoders, data comparators, drivers, counters, shaping circuits, programmable logic devices, microprocessors, microcontrollers, dsp devices.
