Crystal feedback resistor
WebFeedback Resistor Rf The feedback resistor Rf is there to linearize the digital CMOS inverter. Rf accomplishes this feat by charging the inverter’s input capacitance, including C1 from the output of the inverter. In other words, the feedback resistor transforms a logic gate into an ana-log amplifier. Pretty neat trick by simply WebMay 6, 2024 · A ceramic resonator is lossy compared to a crystal and the resistor increases the gain of the inverters forming the clock oscillator to compensate for this loss. The absolute requirement for additional dc feedback is dependent on the resonator as well s the oscillator circuit. Resonators of the same type made by different MFr's may require …
