  • Publication number: 20200007124
    Abstract: An operation adjustment method of an SOI device comprises steps of: (a) obtaining a drain current-substrate bias voltage characteristic of an NMOS transistor for a source-gate voltage of 0V; (b) obtaining a lowest substrate bias voltage which turns on the NMOS transistor from the drain current-substrate bias voltage characteristic; (c) determining an upper limit of a substrate bias voltage of a PMOS transistor as a voltage obtained by subtracting a built-in potential of a pn junction from the lowest substrate bias voltage; and (d) determining the substrate bias voltage of the PMOS transistor as a positive voltage lower than the upper limit. Reduction in the power consumption and maintenance of the radiation tolerance are both achieved for the SOI device.
