.. 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 ...
.. zero (second part of the cycle). This circuit doesn’t tightly control this frequency, which isn’t a critical design parameter; the values in Figure 1 set the frequency to approximately 6 kHz. Q 2 , D 3 , and D 4 prevent V C1 ...
.. recently saw how certain audio power amplifiers can be used as oscillators ( Ref. 1 ). This Design Idea shows how those same parts can be used for simple amplitude modulation, which is trickier than it might ...
.. Woodward, a prolific circuit designer with way more than 100 published Design Ideas (DIs), had his “80 MHz VFC with prescaler and preaccumulator” [ 1 ] published on October ...
