To avoid the uses of multiple RF chain associated with the multiple antennas, RF switch is most essential component. Multiple antennas systems are used to replace traditional single antennas circuitry in the radio transceiver system in order to improve the transmission capability and reliability. The desired switching system must have low cost and simple structure, yet still can capture all the advantage...
This paper reports a highly linear RF sampler with wide operating frequency range and power supply range. A clock bootstrapping circuit is proposed to decrease both the on-resistance and off-leakage of advanced MOSFETs while considering the device reliability. The proposed RF sampler circuit has been implemented in 90 nm CMOS process, and excellent IIP3 has been obtained at wide frequency range up...
