.. V DD /2) squares and triangles. The peak-to-peak amplitude of the latter is fixed by R5 and R6 at 0.909V DD , and the frequency of both is settable over two decades (and perhaps a bit more) by R1C1. Conversion of A2’s ...
.. filter is defined as the ratio of the 3 dB pass bandwidth to the stop bandwidth at some specified attenuation. The center frequency of the bandpass filter in this example is 3 MHz, but this can be adjusted with appropriate LC tank ...
.. and, therefore, the source of 100% error. The obvious approach, using larger resistors, works poorly when you need high-frequency performance. The resulting RC delay products can cause frequency peaking, ringing, and, sometimes, ...
.. and transfer cycle that takes the load to its final voltage. Any attempt to design the converter using a fixed switching frequency results in poorer efficiency. In the case of higher switching frequency, energy transfer would be ...
.. be minimized to reduce power dissipation. For a quick charge of Q2’s gate capacitance C G during turn-on, oscillator frequency should be high (it’s about 900 kHz here). For quick turn-off, R5 should not be too high: the time ...
.. only the coaxial cable between the receiver and the dish to send commands for actions such as changing the low-noise-block frequency range or switching between dishes for multisatellite reception. The DISEqC protocol specifies a bit ...
.. mode, the sum of on-time and off-time gives the switching period of the 1200AP60: where f S is the switching frequency. Extracting L 1 yields If you select a ripple current of 20 mA peak-to-peak at 380 V dc, then From this ...
.. Reference 1 ) or DDS (direct digital synthesis). Digital techniques provide higher stability and the ability to incorporate frequency, phase, and amplitude adjustments. For applications requiring 16-bit or higher-resolution, ...
.. converter in applications 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 ...
