    摘要: A Radio Frequency (RF) front end system and method are disclosed. The RF front end system comprises an antenna, a matching network coupled to the antenna, a power amplifier (PA) coupled to the matching network via a port on a transmit path, a low noise amplifier (LNA) coupled to the matching network via the port on a receive path and at least one transmit/receive switch (T/R SW) coupled between the port and at least one of the PA and LNA.

    摘要: A hybrid circuit (42) for use with communications transceivers. The hybrid circuit (42) combines the function of an ESD protection circuit (12) with the function of a TX/RX switch (10). The input node of the hybrid circuit (42) is connecting between the source of an ESD event (60) and a device to be protected (44). The hybrid circuit (42) includes an ESD protection element (50), which is triggered by a triggering transistor (52). The gate of the triggering transistor (52) is connected to a driver (54) for turning the triggering transistor (52) on during transmission and for turning the triggering transistor (52) off during reception.

    摘要: A biasing scheme for compensating for a difference in biasing currents between a first circuit element (10) and second circuit element (32) in a stacked circuit configuration. A current-difference source (38) generates a difference current that is substantially equal to the difference between the biasing currents of the first circuit element (10) and second circuit element (32) in order to compensate for process, temperature and supply variations.
