    • The present invention relates to an integrated high side gate driver structure for driving a power transistor. The high side gate driver structure (411) comprises a semiconductor substrate comprising a first polarity semiconductor material in which a first well diffusion (426, 430) comprising a second polarity semiconductor material is formed. A peripheral outer wall (430) of the first well diffusion is abutted to the semiconductor substrate. A second well diffusion (427, 429), comprising first polarity semiconductor material, is arranged inside the first well diffusion such that an outer peripheral wall (429) of the second well diffusion is abutted to an inner peripheral wall (430) of the first well diffusion. The integrated high side gate driver structure further comprises a gate driver comprising a high side positive supply voltage port, a high side negative supply voltage port, a driver input and a driver output, wherein the gate driver comprises a transistor driver arranged in the second well diffusion (429) such that a control terminal of the transistor driver and an output terminal of the transistor driver is coupled to the driver input and the driver output, respectively; the integrated high side gate driver structure also comprises a first electrical connection between the first well diffusion and the high side negative supply voltage port and a second electrical connection between the second well diffusion and the high side negative supply voltage port.
