Abstract
An apparatus and a method for generation and adaptive regulation of body bias voltages of an integrated circuit efficiently generates control voltages for active body biasing The apparatus includes a digital circuit, a counter, a control unit and at least one charge pump. The control unit and the digital circuit are connected in a closed control loop, and the digital circuit comprises at least one hardware performance monitor to monitor a timing of a body bias voltage. The control loop is formed by a control path comprising the at least one charge pump, the hardware performance monitor and the control unit. The charge pump is controllably connected to the control unit to adjust the charge pump for generation and adaptive regulation of the body bias voltage according to a timing frequency difference between an output signal of the hardware performance monitor and a reference clock signal.
