Abstract

The invention discloses a reinforcement circuit for a long distance transmission driver, comprising a clkin input end and a clkout output end. The clkin input end and the input end of a reinforcement inverter inv1 are connected, the output end of the reinforcement inverter inv1 is connected with the input end of a reinforcement inverter inv2, and the output end of the reinforcement inverter inv2 is connected with the clkout output end. The invention also discloses a clock line long distance transmission circuit. The anti-nuclear radiation reinforcement circuit of the long distance transmission driver in the anti-nuclear radiation chip of the invention has the output voltage reaching the rail voltage requirement under the nuclear radiation environment, greatly enhances the robustness of the NMOS tube and effectively overcomes the bias-removing effect of the substrate.

Description

technical field [0001] The present invention relates to the technical field of reinforcement design of the driver (BUFFER) during the long-distance transmission of the clock line, the set line, the reset line and various data and control lines in the anti-nuclear radiation chip, in particular, it relates to a long-distance transmission The driver reinforcement circuit and the long-line transmission circuit of the clock line. Background technique [0002] With the enhancement of my country's comprehensive national strength, the key technical equipment for nuclear accident\nuclear war rescue has risen to the top priority of the national strategic technical equipment reserve! Nuclear accident\nuclear war rescue equipment, technically speaking, can be divided into Two key levels: one is anti-nuclear radiation chip technology and anti-nuclear radiation hardening technology for electronic information systems, and the other is intelligent unmanned equipment with anti-nuclear technol...
