Split-transistor compensation: Analytical model

Split-transistor compensation (STC) is introduced as a new compensation technique applicable to power management of Internet-of-Things (IoT) devices. An extension of the split-length compensation (SLC) technique [1]-[3], STC significantly reduces the area of the required on-chip compensation capacitor, while maintaining the two major benefits of SLC: reduced minimum supply voltage and no additional power consumption. We develop equations to model split-transistor behavior in a compensation network and verify the proposed novel analytical model via simulations using foundry transistor models.
