- .. is roughly 100 kHz under control of the U1c Schmidt trigger style oscillator, so that a charge transfer occurs every 10 µs. Note the positive feedback around U1c via R3 and inverse feedback via R1, R2, and C1. The resulting ...
.. at and below zero volts, generating symmetrical output signals, and processing bipolar analog inputs, are all examples of design situations where a few milliamps of negative voltage rail can be a necessity. Figure 1 shows a simple ...10-01-2024
- .. by R6 and D6, which track R1 and D2 in the oscillator itself. A4 buffers the output, which is now almost constant below 10 kHz and only 10% up at 25 kHz. (LDR1 was a Silonex NSL-19M51, the LED being a generic T-1 clear white 8 cd device, ...09-01-2024
- .. on, what of the others? A simple twin-tee notch filter with feedback, built for close to 1 kHz with a Q of 2 and a gain of 10, allowed the scope’s rather basic FFT to reveal harmonics previously buried in the sampling noise. This clearly ...
.. exponential waves are much use for generating sines, especially when their amplitudes depend on the supply. (My original design spec was for a PP3/6LR61 battery, giving about 9 V or 4.5 V when new, and a lot less when not.) A different ...08-01-2024 - .. associated with the circuit in Figure 1. T 1 is a signal transformer that you can modify by wrapping two turns of 14-gauge wire around the bobbin to act as the primary winding. Materials on the topic Datasheet Texas Instruments LM311 ...
.. Note that the signal ground with respect to earth ground is floating; you must not tie these grounds together. The design in Figure 1 has successfully controlled fans and high-amperage universal motors (100 mA to 11 A). One example ...01-01-2024 - .. back I published a simple design idea for a thermal airspeed sensor based on a self-heated Darlington transistor pair ( Ref. 1 ). See Figure ...29-12-2023
- .. 3 V, the linear driver takes over. Note that if the other half of the LM393 is not used for another LED power supply, good design practice dictates that all unused input and output pins on the LM393 be tied to ground. Figure 2 shows the ...28-12-2023

- .. dubious) advantages compared to competing topologies. This “new” (I haven’t seen it elsewhere) idea for a design shown in Figure 1 joins the mob with the following claims to fame. It requires only a single amplifier, runs ...22-12-2023
- .. the best output I was able to get with this “photocell” is more than 0.81 V at R LOAD = 2k and 2 × 5 = 10 mA of total current through LEDs (super bright of OSRAM). This was quite enough for my application, but it was ...
.. zero output of an op-amp that is based on a symmetrical multivibrator for better efficiency than the previous photocell design idea. This second circuit is based on a symmetrical multivibrator and has far better efficiency than its ...19-12-2023 - .. C REF = 500 pF and V REF = 2.5 V, this circuit has a gain of 5 mV/pF, and when measured with a DMM achieves a resolution of 10 fF for a dynamic range of 100 dB. It also rejects stray capacitance (shown as ghosts in Figure 1) by 100 dB. If this ...18-12-2023
