  • Leakage compensated electronic switch
    Patent number: 8253474
    Abstract: An electronic circuit for switching purposes comprises a set of at least four electronic switches. A first subset and a second subset comprise at least two electronic switches of said set, respectively. Said at least two electronic switches of said first subset are arranged in a serial connection. Said at least two electronic switches of said second subset are arranged in a serial connection. The electronic circuit comprises a first buffer connected to a first electronic switch of said first subset and a second buffer connected to a second electronic switch of said second subset. Said first buffer minimises a potential drop across said first electronic switch when in open state, and said second buffer minimises a potential drop across said second electronic switch when in open state. The electronic circuit further comprises a switched connection towards ground arranged in between the two subsets.
