In this paper we present an asynchronous finite-state machine digital controller co-integrated with an on-chip non-inverting buck-boost power converter with dynamic signal-tracking capabilities. The mostly-digital controller ...

This paper presents an output-capacitorless low dropout (LDO) regulator based on improved flipped voltage follower power stage for use in power management circuits. A new error amplifier (EA) structure, named as gain-bandwidth ...

The effect of using a tuning inductance on the performance of a Gilbert cell-based two level transistor CMOS sub-harmonic mixer is investigated. The tuning inductor used between the RF and LO switching stages causes ...

Digital control of power converters has been an area of considerable research interest in recent times. One of the problems which arises in these systems is that of the limit cycle oscillations that occur due to ...

This paper is devoted to the design of a sliding-mode control scheme for a buck-based inverter, with programmable amplitude, frequency, and dc offset, with no external sinusoidal reference required. A general procedure for ...

The need for autonomy in several fields of aerospace engineering has become apparent and widely accepted during the last decade. Autonomy promises to improve the systems' performances, their robustness and tolerance to ...

Spaceborne constellations composed by several heterogeneous platforms are an actual solution to undertake Earth Observation missions. However, designing such missions present problems due to the heterogeneity and the ...

Earth observation satellite programs are currently facing, for some applications, the need to deliver hourly revisit times, sub-kilometric spatial resolutions and near-real-time data access times. These stringent requirements, ...
