Abstract:
A charge pump output stage, comprising:an input node, a second node, a first clock node, and a second clock node; a first transistor, wherein said first transistor is an N channel metal oxide semiconductor field effect transistor having a source connected to said input node, a gate, and a drain connected to said second node; a second transistor, wherein said second transistor is an N channel metal oxide semiconductor field effect transistor having a source connected to said input node, a gate connected to said drain of said first transistor, and a drain connected to said gate of said first transistor; a first diode having an anode and a cathode wherein said cathode of said first diode is connected to said drain of said first transistor; a second diode having an anode and a cathode wherein said anode of said second diode is connected to said drain of said first transistor and said cathode of said second diode is connected to said anode of said first diode; a first capacitor connected between said first clock node and said anode of said first diode; and a second capacitor connected between said second clock node and said drain of said second transistor.
