Capacitors

This paper proposes an output-capacitorless low-dropout regulator (OCL-LDO) with simple structure and fast load transient response for system-on-chip applications. The proposed OCL-LDO does not require output capacitance and remains stable at no-load condition.

In the paper, 3L-MPC algorithm with fast calculation is proposed to control many objectives such as unit power factor, capacitor voltage balance and switching frequency reduction. In addition, the outer PI controller is used to adjust the DC-bus voltage. The simulation results demonstrated the excellent performance of the proposed method, both in transient and steady states.

Power and Energy Power is drawn from a voltage source attached to the VDD pin(s) of a chip. Instantaneous Power: P (t ) = I (t )V (t ) Energy: Average Power: 7: Power – Half the energy from VDD is dissipated in the pMOS transistor as heat, other half stored in capacitor When the gate output falls – Energy in capacitor is dumped to GND – Dissipated as heat in the nMOS transistor
