Area efficient LV NMOS TWL charge pump

A method of generating a voltage waveform having an amplitude three times an input voltage amplitude using a plurality of low voltage (LV) triple well (TWL) N-type field effect devices, the method comprising:

• receiving a first input voltage at a first input of a double switch charge transfer switch (CTS) circuit, the double switch CTS circuit comprising a first portion having a first output and a second portion comprising a second output;
• applying a 2× kick voltage to a first capacitor coupled to the first portion of the double switch CTS circuit, the first capacitor configured to discharge a kick voltage to a source of a first LV TWL N-type field effect device of the plurality of LV TWL N-type field effect devices;
• and
• applying a 1× kick voltage to a second capacitor coupled to the second portion of the double switch CTS circuit, the second capacitor configured to discharge a kick voltage to a source of a second LV TWL N-type field effect device of the plurality of LV TWL N-type field effect devices.
