Integrated, high speed, zero hold current and delay compensated charge pump

A digitally controlled charge pump, including:

• first and second supply terminals;
• first input terminal means for receiving first digital charge control signals;
• second input terminal means for receiving second digital charge control signals;
• an output terminal;
• first transistorized differential amplifier means including first control input terminal means coupled to the first input terminal means and second and third terminal means defining a first main current flow path and coupled between the first supply terminal and the output terminal, for controlling a first current flow of a first polarity between the first supply terminal and the output terminal through the first main current flow path as a function of the first control signals;
• second transistorized differential amplifier means including a first control input terminal means coupled to the second input terminal means and second and third terminal means defining a second main current flow path and coupled between the first and second supply terminals, for controlling a second current flow between the first and second supply terminals through the second main current flow path as a function of the second control signals;
• and
• transistorized pump current mirror means including first and second terminal means connected in series with the record main current flow path of the second differential means and third and fourth terminal means coupled between the output terminal and the second supply terminal, for producing and controlling a mirrored second current flow of a second polarity between the output terminal and the second supply terminal as a function of the second current flow.
