Title:
LOGIC CIRCUITS
Document Type and Number:
WIPO Patent Application WO1997009785
Kind Code:
A3
Abstract:
A logic circuit having at least a first input terminal and at least a first output terminal, comprises at least a first and a second electron-wave Y-branch switch, each having a source, a first drain, a second drain, and at least a first gate for switching a source current between the first and the second drain. The sources of said first and second Y-branch switches are adapted to be connected to a high voltage supply and a low voltage supply, respectively. The first gates of said first and second Y-branch switches are interconnected, and the interconnection point between said first gates constitutes said first input terminal. The first drain of the first Y-branch switch is connected to the second drain of the second Y-branch switch, and the second drain of the first Y-branch switch is connected to the first drain of the second Y-branch switch. The interconnection point between said second drain of the first Y-branch switch and said first drain of the second Y-branch switch constitutes said first output terminal.
