摘要: A calibration circuit (20, 50) and method (60) for calibrating the bias current of a VCO (10, 40) to minimize phase noise. The calibration circuit (20, 50) monitors the average voltage at the common-mode node of the VCO (10, 40) while varying the bias current over a predetermined range. The calibration circuit (20, 50) identifies the bias current associated with the minimum average common-mode voltage and utilizes this bias current for calibrating the biasing transistor of the VCO (10, 40).

摘要: A distributed electrostatic discharge (ESD) protection circuit for high frequency integrated circuits. A transmission line from an integrated circuit (IC) pad or package pin couples a plurality of ESD elements. The ESD elements, such as diodes, are distributed along the transmission line and coupled from the transmission line to ground or a power supply. The effective impedance of the transmission line and ESD elements is defined to match the impedance of an external line. Distributed ESD protection circuits provide a high frequency signal path that can be used well into the GHz frequency range and also provide effective ESD protection.

摘要: A wireless (such as Wi-Fi or similar) access point is included in or attached to a device, such as a cellular phone, WiMAX device, other mobile device, etc. One or more wireless units wirelessly access a communication network (and in some cases the Internet) through the wireless access point device. Additionally, such a wireless access point device can receive a transmission from a wireless tag that has been attached to an object to be monitored and can forward information from the wireless tag to a target device along with location information.

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.
