.. than 0.2 µA. This constraint implies that R 4 ’s value is less than 6.12 MΩ. The triangular-waveform frequency is: For this example, the frequency is 25 kHz, the output voltage is 4 V p-p, or 0.5 to 4.5 V for a ...
.. a periodic change of the hue. If you set the Preset high and hold the /PU pin low while feeding a 50%-duty-cycle, 0.05-Hz-frequency logic waveform to the /PD pin, you get a slow, periodic, quasicontinuous “waving” of the ...
.. R2 to the 212 mV reference. The amplifier drives Q1, which modulates current into the I LIM pin. This varies oscillator frequency to control average current. Overall frequency compensation is provided by R1 and C1, values carefully ...
.. often choose a super-regenerative receiver despite its frequency instability and poor selectivity for battery-powered, short-range, wireless applications in which power ...
.. LED from one cell without an inductor. РFigure 1. Resistors R 1 and R 2 and capacitors C 1 and C 2 set the oscillation frequency. Transistors Q 1 , Q 2 , Q 3 , and Q 4 form the H bridge, which acts as a simple charge-pump converter ...
.. can operate with almost any resistive transducer based on a Wheatstone bridge. The circuit comprises a VFC (voltage-to-frequency converter) that produces a PPM (pulse-position-modulation) output, and an OOK (on/off-keyed) RF ...
.. design idea with a 555 analog timer that can generate an arbitrary triangle/sawtooth with its waveshape and frequency controlled by pots. If you could assemble the list of all the oscillators that have been designed ...
.. time to a load change is less than one switching cycle. What's the catch? You must be able to accept a switching frequency that is not precisely controlled and a sensitivity to noise that requires layout skill. Figure 1 shows ...
.. becomes The output voltage is Both the input voltage and the digital-input data can be time variables, and the clock frequency for fetching digital-input data can be as high as 50 MHz. Figure 1. The resistive DAC-potentiometer ...
