How can a BJT be used as a diode? The emitter-base junction acts as a simple semiconductor diode. Simply connect the base of the transistor…
What makes a ground a ground? In electronic circuit theory, a “ground” is usually idealized as an infinite source or sink for charge, which can…
What is the mechanism of LED? LED is an abbreviation of Light Emission Diode, and is a device which emits light by flowing a current…
How do you select a Hall sensor magnet? A Hall effect sensor typically operates using only the north or south pole of the magnet. A…
What is encoder index pulse? The index pulse signals when the encoder shaft completes a single revolution. An index pulse is used for precision homing…
Is it possible to make your own QSYS components? The Qsys tool includes many pre-designed components that may be selected for inclusion in a designed…
How does a peak detector work in a circuit? In this circuit, the amplifier compares the input signal with the capacitor voltage so that if…
What is this white stuff on my circuit board? The white residues themselves usually (but not always) are salts, which are the “activators” in the…
What are the output channels of a quadrature encoder? A quadrature encoder is an incremental encoder with 2 out-of-phase output channels used in many general…
Can electric cars have turbos? While automakers have gotten better at reducing turbo lag, delivering response close to that of naturally aspirated engines, electric turbochargers…
