This temperature controller employs an LM135/235/335 temperature sensor, can be used to keep small environment warm or hot. Here is the schematic diagram: LM311 is used as comparator, to detect if the voltage at sensor pin (the inverting input) goes higher than the reference pin (the non-inverting pin). If this condition is …
Read MoreCrystal oscillator, especially the low frequency one, can be easily implemented using op-amp as the amplifier. Here is the schematic diagram of such circuit: [Source: National Semiconductor Application Note]
Read MoreOne example of the phase shift oscillator is Bubba oscillator. This oscillator gets 45 degree phase shift for each section from quad op-amp package. The result is excellent d(phase)/d(t) to obtain very low frequency drift. The circuit is shown below: 45 degree phase shift is obtained from Each RC section. The alternating …
Read MoreThis is a Sine Wave Oscillator circuit. This circuit as known as amplitude-stabilized sine-wave oscillator. It can gives high purity sine-wave output down to low frequencies with minimum circuit complexity. This circuit has a several advantages such as it does not use the traditional tungsten filament lamp amplitude regulator, so the problem problems associated with …
Read MoreQuadrature oscillator is another type of phase shift oscillator. This circuit produce two sine wave signal. One of them is shifted 90 degree from the other signal. The output that shifted 90 degree is called cosine signal and the other is called sine circuit has two output. Here is the circuit : This …
Read MoreWhat is a PLL oscillator? PLL stands for phase locked loop, and this means a control method by comparation of the controlled plant or system to a reference clock or oscillator, that the plant is controlled to synchronize the clock. PLL has been widely implemented in motor control application, to make the motor rotates …
