Document Type and Number:
WIPO Patent Application WO/2017/089726
Kind Code:
A3
Abstract:
The invention relates to a DC-to-DC converter block with multiple supply voltages, comprising a power circuit, said power circuit comprising N depletion-mode HEMT transistors (T3_1, T3_2, T3_N), N being a natural number greater than or equal to 3. The DC-to-DC converter block also comprises a gate drive circuit for the N depletion-mode HEMT transistors (T3_1, T3_2, T3_N) of the power circuit. The invention is characterised in that the drive circuit comprises depletion-mode HEMT transistors (T1_1, T2_1, T1_2, T2_2, T1_N, T2_N) configured to drive the gates of the N depletion-mode HEMT transistors (T3_1, T3_2, T3_N) of the power circuit, and in that the power circuit is powered by N positive and non-zero supply voltages, namely a lower supply voltage (VDD_1), an upper supply voltage (VDD_N), and (N-2) intermediate supply voltages (VDD_2) distributed between the lower (VDD_1) and upper (VDD_N) supply voltages.
