  2. Fig 1’s circuit, which was developed to monitor the traffic of bumblebees into and out of the hive, differentiates “a-to-b” motion from “b-to-a” motion. When used with an optical decoder, the circuit distinguishes ...

  1. This Design Idea describes a new class of logic gates, which we have named resistor-FET-logic, aka “RFL.” How do we know it is new? While FET switches are common today, we have been unable to find a similar resistor-FET-logic. Further, ...

  3. This Design Idea is an evolution and simplification of another (Figure 1, Reference 1 ). Replacing the three inverted-input NOR gates with their logical equivalents, positive-input NAND gates, makes these three gate symbols consistent with the ...

  6. Introduction In some applications it is necessary to transmit square waves across a long cable. However, long cables typically have high capacitance, which can significantly affect the signal’s wave shape. As such, the signal’s ...

  7. When driving an H-bridge or a similar circuit, you usually must ensure that two or more transistors are not on at the same time. Eliminating multiple transistors from turning on reduces power consumption and lowers EMI (electromagnetic ...

  8. Circuits Digital Maxim MAX6369 MAX6847
    Mechanical push-pushbutton switches (also known as alternate-action or push-on/push-off switches) can be bulky and expensive. As an alternative, an electronic version uses a cheaper, NO (normally open), momentary-on switch (Figure 1). Figure 1. ...
