  • Power-on reset circuit
    Patent number: 6744291
    Abstract: A power-on reset (POR) circuit comprises a transistor connected ad diodes for setting temperature time delay coupled to a power supply voltage, a transistor switch, and buffering circuits. The trip point voltage of the POR circuit depends only on one type of transistor, such as the switching transistor so that the p-to-n skew variations do not affect the trip point. The switching transistor has a resistor connected from base to ground and another resistor connected to the power supply voltage to limit current flow during transitions.
    Type: Grant

    Date of Patent: June 1, 2004
    Assignee: Atmel Corporation
    Inventors: James E. Payne, Harry H. Kuo, Neville B. Ichhaporia, Jami N. Wang
