Abstract
A charge pump comprises one or more pump stages for providing a negative boosted output voltage. Each of the one or more pump stages comprises a P-channel transistor formed in an isolated P-well and an N-channel transistor coupled in series with the P-channel transistor. Forming the P-channel transistor in the isolated P-well essentially eliminates a raised threshold voltage due to body effect.
