Capacitor Charge Sharing
When reading about charge pumps you will encounter a phrase like "they act like resistors". The following example demonstrates why they say that. So each capacitor ends up with 1/2 Volt on it. That means the system starts with 1/2 Joule of energy and when the transfer of charge is done Read more…
