- Stephen Woodward.. really merits separate publication in the first place. Fortunately, this is not quite the end of our story. Because of the 10% attenuation of the PRT signal inflicted by the passive side of my bridge, in order to duplicate Nick’s ...Oct 1, 2024
- Stephen Woodward.. several times faster than commercially available VFCs (e.g., the 4-MHz VFC110) while conveniently running on less than 10 mA from a single +5-V supply/reference. Figure 1. Take-back half (TBH) charge pump gives simple VFC reasonable ...Sep 30, 2024
- Alexander Bell.. to electromagnetic damping of the meter movement. For example, suppose that your application requires measurement of a 0 to 10 V power supply (Figure 1). You have available a typical electromechanical meter that presents a full-scale voltage ...Sep 30, 2024
- Jayapal Ramalingam.. This simple, inexpensive circuit is basically an oscillator, divide by 4096 counter and followed by another divide by 10 circuit. The equation below can be used to obtain the time delay, T, in seconds. Where F is the U1 (555) oscillator ...Sep 26, 2024
- Nick Cornford.. accordingly. This ( Ref. 3 ) is a useful tool for doing so. Lastly, there is the DMM with which this will be used. The 10-MΩ input resistance of most meters will introduce only a tiny error, which will be compensated for during ...Sep 25, 2024
- Stephen Woodward.. output of a popular µP I’ve been using is configured to be a constant logic low or high and is loaded only by a 10 MΩ-input digital multimeter, the voltage levels are in some cases more than 100 mV from supply voltage V DD and ...Sep 23, 2024
- Stephen Woodward.. force hotwire heating to match the setpoint dialed in on R5. The result is good temperature control, but also up to 10 W of dissipation on Q1. In Figure 1, by contrast, positive feedback around A1a via R7 forces the amplifier to latch ...Sep 18, 2024
- Peter Demchenko.. Figure 2. The circuit produces short (less than 1 µs) current pulses through the capacitor C X with a period of about 10 µs; the voltage drop on the capacitor (V ESR ) is proportional to its ESR. So, comparing this voltage drop with ...Sep 17, 2024
- Dale LitwhilerYou can use the simple sensor circuit in Figure 1 to remotely monitor the level of liquid water in a vessel such as a swimming pool. The LMC555 sensor oscillator provides an output-signal frequency that is a function of the water level. This signal ...Sep 2, 2024
- Fons Janssen.. the circuit’s efficiency. As Figure 5 shows, the adjusted feedback of Figure 3 increases the efficiency more than 10% at either half-load or full load. Assuming that the sense voltage doesn’t change, efficiency improves for ...Aug 27, 2024
