Triode:
BJT (Triode): Bipolar transistor, widely used for signal amplification and switching.
FET (field effect transistor): such as MOSFET and JFET, mainly used in high-frequency amplification and switching circuits.
Integrated circuit (IC):
Components with multiple circuit functions can be the integration of analog (such as operational amplifiers) or digital circuits (such as microcontrollers and logic gates).
Common IC includes operational amplifier (such as LM741), analog switch, signal conditioning circuit and microprocessor.
Photoelectric element:
Light-emitting diode (LED): It can convert electric energy into light energy and is widely used for display and indication.
Laser diode: used in applications that require highly concentrated beams, such as laser printers and optical fiber communication.
Photoelectric sensors: such as photoresistors and photomultiplier tubes, are used in photoelectric detection and imaging.
Relay:
An electrical device used to control the switch of a circuit, which can control a large current through a small current.
Operational amplifier:
A multipurpose analog integrated circuit, which is widely used in signal amplification, filtering and signal processing.
Mixed signal circuit:
Integrated circuits that process both analog and digital signals, such as analog-to-digital converters (ADC) and digital-to-analog converters (DAC).
Power management IC:
Integrated circuits for regulating and managing power supply, including linear regulators, switching regulators, etc.
All kinds of active components have specific functions and applications in different circuit designs, and can realize signal amplification, processing, conversion and control.
