The chip is a new fully integrated DC-DC converter featuring on-chip orthogonally placed 8-shaped stacked transformers for miniaturized power delivery. It achieves power conversion efficiency up to 78.1% and peak power density of 0.42W/mm^2 delivering 23uW-0.3W output power. The proposed on-chip transformer design minimizes the magnetic field intensity outside of its borders, mitigating issues such as parasitic coupling, local oscillator pulling and EMI, demonstrating a measured 27dB reduced magnetic interference.
