Abstract

A Charge Pump Avoiding Gain Degradation Due to the Body Effect. A charge pump having a first input and a first output, a stage of the charge pump including a first capacitor having a first node and a second node, the second node coupled to receive a first signal; a first p-type transistor having a first gate, a first source, and a first drain, the first gate being coupled to the first node and the first drain, the first source being coupled to the first input; a second capacitor having a third node and a fourth node, the fourth node coupled to receive a second signal; and a second p-type transistor having a second gate, a second source, and a second drain, the second gate being coupled to the third node and the second drain, the second source being coupled to the first drain, the second drain being coupled to the first output.
