    Abstract: The present invention is a novel and useful RF transformer based transmit/receive (TX/RX) integrated RF switch. In one embodiment of the invention, the TX/RX RF switch circuit is based on the use of an RF transformer which functions as (1) the PA output transformer during TX mode and (2) as a series inductance in an LNA matching network during receive mode. Thus, the RF transformer plays a dual function or role. Antenna diversity is achieved by having multiple antennas each having an associated antenna switch connected to the output transformer. The TX/RX switch of the invention reduces the number of switches required for antenna diversity to a minimum and minimizes RF losses in the system. The TX/RX switch is suitable for use with modern wireless communication standards such as DECT, 802.11 WLAN, Bluetooth, ZigBee, etc. The configuration of the TX/RX circuit permits the use of common, relatively low cost semiconductor fabrication techniques such as standard CMOS processes.

    Abstract: In a mobile device, a bone conduction or vibration sensor is used to detect the user's speech and the resulting output is used as the source for a low power Voice Trigger (VT) circuit that can activate the Automatic Speech Recognition (ASR) of the host device. This invention is applicable to mobile devices such as wearable computers with head mounted displays, mobile phones and wireless headsets and headphones which use speech recognition for the entering of input commands and control. The speech sensor can be a bone conduction microphone used to detect sound vibrations in the skull, or a vibration sensor, used to detect sound pressure vibrations from the user's speech. This VT circuit can be independent of any audio components of the host device and can therefore be designed to consume ultra-low power. Hence, this VT circuit can be active when the host device is in a sleeping state and can be used to wake the host device on detection of speech from the user. This VT circuit will be resistant to outside noise and react solely to the user's voice.
