- Marián Štofka.. in which power efficiency is a critical issue. The two phases of operation repeat periodically at frequency f, which clock generator IC 2 determines. The duty cycle is about 50%, but the value isn’t all that critical. One half ...Oct 19, 2023
- Stephen Woodward.. two loops are essentially identical, let’s talk about the OG loop. Each timing sequence begins when U1pin8 delivers a clock pulse to U3 pin . U3 is positive-edge-triggered and responds by driving U3 pin 6 low. This disconnects D2 from ...Oct 10, 2023
- R O Ocaya.. source. In Figure 2 the load resistor of Q2 is switched into or out of the collector by an extra transistor, Q3 driven by a clock source V 3 having 50% duty cycle. Thus the load resistance variably has the value R1 when V 3 = 5 V and (R1 + ...Oct 3, 2023
- Chuck Wojslaw Gary M Craig.. of S 1 . The potentiometer's wiper advances on the falling edge of the signal driving the /INC input of the DPP. The clock output of IC 1D drives /INC. The clock becomes enabled when you depress the rocker switch either up or down. ...Sep 21, 2023
- Anthony Di Tommaso Ljubisa Milojevic.. on the comparison match of a preset count. You base the count on the desired frequency output and the timer's internal clock rate. You then adjust the output of the microcontroller's timer to remove offset. You need to eliminate as ...Aug 31, 2023
- Jim Williams.. fed circuit, reduces gain TC to 8 ppm/ C and achieves 15 ppm linearity by replacing the capacitor with a quartz-stabilized clock. Figure 1. 5 V powered, quartz-stabilized 10 kHz V-F converter has 0.0015% linearity and 8 ppm/ C temperature ...Aug 29, 2023
- Jim Williams.. The demodulator DC output is buffered by chopper stabilized A2 which provides the circuit output. A2’s internal 1 kHz clock, level shifted by Q2, drives the CD4040 frequency divider. One divider output supplies the 0.5 Hz square wave; ...Jun 22, 2023
- Jim Williams.. LTC6943 -based charge pump. The charge pump’s two sections operate out-of-phase, resulting in charge transfer at each clock transition. Charge pump stability is primarily determined by the LT1460 2.5 V reference, the switches low ...May 12, 2023
- Luca Bruno.. that comes with asynchronous preset and clear inputs because they have the same function as the set/reset inputs when the clock and data inputs are grounded. This method functions only with CMOS-logic families that offer the benefits of ...Apr 27, 2023
- Jim Williams.. switching regulator to form a high voltage switched mode control loop. The LT1072 pulse width modulates Q1 at its 40 kHz clock rate. L1’s inductive events are rectified and stored in the 2 µF output capacitor. The 1 MΩ ...Apr 21, 2023
