A low-noise, positive-input, negative-output voltage generator for low-to-moderate driving capacity applications

In this paper, a generic, low-noise, negative-voltage generator with wide tuning range and moderate driving capacity is presented. The highly integrated solution, incorporating a fully-integrated charge-pump and a regulator block, requires only one off-chip capacitor that can be shared with the sup...
