      What is a CMOS Inverter?

      A CMOS (Complementary Metal-oxide Semiconductor) inverter is a device that produces logic functions and is the primary component of all integrated circuits. A CMOS inverter is a field-effect transistor that is composed of a metal gate that lies on top of an insulating layer of oxygen, which lies on top of a semiconductor. CMOS inverters

      How Sunspots Affect Radio Reception

      In order to understand how sunspots effect radio reception, you need to understand that the light waves and radio waves that the sun emits are both categorized as electromagnetic (EM) radiation. While light waves are visible to the human eye, they are still electromagnetic waves that oscillate. There are many electro magnetic waves, some oscillate

      BJT Transistors

      Basic diodes are constructed from two semiconductor materials, germanium or silicon, to create a basic PN-junction. When two single diodes are connected to each other back-to-back, two PN-junctions that are connected in series are created. They share a common N or P terminal, which forms the basis of a BJT or Bipolar Junction Transistor. The

      TRIAC

      A TRIAC is used in AC power control applications in order to switch high voltages over both parts of the AC waveform. As a result, TRIAC circuits are used in a number of applications that require power switching. The TRIAC was developed after the thyristor, which controls AC current over one half of the cycle.
