.. a cycle that begins with C2 being charged to V IN via U1a, then completes by partially discharging C2 into C3 via U1b. Pump frequency is roughly 100 kHz under control of the U1c Schmidt trigger style oscillator, so that a transfer occurs ...
.. output. A rather low value of inductance (0.1 1.0 mH) is sufficient. (This low value may be counter-intuitive to the low frequency of the multivibrator, which is less than 1 kHz.) The negative output voltage slowly increases with an ...
.. classic and versatile 555 finds its way into many low to moderate frequency oscillator applications. Some of these require the ability to selectively gate oscillation on and off ...

.. is a square wave, with an exponential tri-wave present on C T . While the duty cycle is exactly 50% and the operating frequency is stable with supply variations assuming balanced power rails and a rail-to-rail op-amp output neither ...
.. trigger early by an amount proportional to anti-log Q2’s collector current. This shortens VFC period and raises VFC frequency by a nonlinearity-correcting factor and results in Figure 6. Figure 6. Improved analog linearity ...
.. especially when the supply voltage drops and approaches the LED forward voltage. In automotive applications, RFI (radio-frequency interference) is a major concern. EMI/RFI filters are recommended in front of the switching converters ...
.. quadrature signals are summed, the result is an approximate (roughly 3% nonlinearity) triangular waveshape at double the frequency of the sine, with amplitude proportional to the sine’s. Adjustment of the quasi-triangle’s ...
