.. for its reference. As anticipated, its display shows that the average output frequency is the 32.768 kHz specified by the design. The divider circuit’s output pulse train was also recorded on a Keysight DSO-X 1102G oscilloscope as ...
.. incorporate PWM control of the output voltage requires some thought, and both Stephen Woodward and I have presented several Design Ideas (DIs) that address this. I’ve suggested disconnecting R G from ground and driving it from a ...
.. the resistor-ratio change, IC 1 ’s output voltage ramps up to its final I/O-voltage value of 3.3 V. The MOSFET this design uses has an on-resistance of roughly 10 Ω. This figure might sound high, but, because of the ...
.. recently published a simple design ( Ref. 1 ) for a platinum resistance detector (PRTD) 4 to 20 mA transmitter circuit, illustrated in Figure 1. ...
.. or sketchy low-end options, this post is for you. The tried-and-true preliminary schematic In Figure 2 shows you how to design and build your own ATS using a handful of analog components you may already have in your parts bin. Figure 2. ...
.. Usually a fuse, resettable or non-resettable, protects the system, but it is not always accurate or fast enough. This Design Idea shows a way to safeguard a boost converter from short circuits and reverse polarity application (Figure ...
.. contained within an inexpensive CD4007UB IC. The circuit is inspired by a classic bipolar emitter coupled oscillator design and works in much the same way. The first N channel transistor is biased to the mid-supply point. The gate of ...
