  • Reduced power consumption bi-directional buffer
    Patent number: 6590433
    Abstract: A bi-directional buffer includes the capability to turn the current mirror off when the bi-directional buffer is in the receive mode and quickly turn the current mirror on when the bi-directional buffer goes into the transmit mode. This is accomplished in part by a pair of switches included in the current mirror, which are controlled by enable signals. The switches are configured such that the output transistor of the current mirror is turned on when the bi-directional buffer is in the transmit mode, and turned off when the bi-directional buffer is in the receive mode. Further, a pull up circuit may be added to the current mirror to more quickly bring the gate of the output transistor of the current mirror to its conduction threshold voltage.
