CMOS OUTPUT DRIVER USING FLOATING WELLS TO PREVENT LEAKAGE CURRENT |
摘要 |
An I/O buffer circuit including: a driver circuit containing a pull-up device in a first floating well and a pull-down device in a second floating well; a first and second biasing circuits to bias the first and second floating wells in response to voltages internal and external to the I/O buffer circuit; and a first and second tracking circuits to bias each of said pull-up and pull-down devices in response to voltages internal and external to the I/O buffer circuit in a shutdown mode.
