.. in the feedback path of a switched-mode power supply. The CTR determines the DC gain of a power supply’s open-loop frequency response, which affects the loop’s phase margin. An optocoupler influences multiple operating ...
.. methods for analog to digital conversion are more “mature” than the classic combination of a voltage-to-frequency converter (VFC) with a counter. VFC digitization is naturally integrating, so good noise rejection is ...
.. asymptotically approaches the comparator output voltage with a time constant RC. This time constant RC determines the frequency of the oscillation. The duty cycle of the signal can be adjusted by changing the ratio of resistance of ...
.. capacitor C2 is reduced by several orders of magnitude. This makes the current pumped directly proportional to oscillator frequency: Starting from that idea, then adding some simple discrete components, our original inverter circuit ...
.. voltage is typically larger than the differential input voltage. The effectiveness of the rejection diminishes as the frequency of the common-mode voltage increases. Amplifiers within the same package have better matching, the same ...
.. IN+ and IN pins. In this case, the gain resistors become part of the input resistance for the source. The differential-mode frequency response plot was taken by applying a differential input voltage at the two input terminals (IN+ and IN ...
.. to the feedback gain to stabilize the circuit and maximize the system bandwidth. The following equation calculates the pole frequency, f P : The following equation determines the zero frequency, f Z : Figure 3. The circuit in Figure 2 ...
.. Darlington pair” ( Ref. 2 ) and in Figure 1. Figure 1. Constant-temperature anemometer with direct power-to-frequency conversion. Figure 1’s anemometer is unusual because it melds the sensor transistor into a direct ...
.. cutting the ripple to a quarter of the single-phase value. That ripple will also be at four times the fundamental frequency, so we are (roughly) sixteen times better off than we were with the Wien bridge. With ...
.. levels down to 0.0003% (3 ppm) can be achieved, so we have one benchmark, though that’s most likely for a spot frequency rather than for a multi-range, fully-tunable device. A practical target is 96 dB or 0.0015%, which is ...
