Pre-emphasis pulse
I hope you can get a clear image of how the pre-emphasis pulse can significantly reduce the RC delay time through the following animations.
1) Step pulse vs. pre-emphasis pulse
Top: RC line driven by Vin
Middle: Waveform at the mark with a step pulse
Bottom: Waveform at the mark with a pre-emphasis pulse

2) Optimum vs. non-optimum
Voltages vs. position (zero indicates the nearest and one indicates the farthest) with pre-emphasis times of Topt X 0.8 (the left most), X 1.0 (center) and X1.2 (the right most)  Created by Matsuyama

3) Voltages vs. position (zero indicates the nearest and one indicates the farthest) after an optimum pre-emphasis time. Wave components with different wave numbers (k) vary at different time scales (exp(- k^2 t). Created by Matsuyama

Charge pump
– Multiple capacitors and diodes connected in series between the input VDD and the output LOAD
– Capacitors driven by anti-phase clock clock alternately
I hope you can get a clear image of how the charge pump gradually increases the voltage from input to output through the following animation.
