    摘要： Systems, methods, and apparatuses are provided for fine-sensing modules that are operative for identifying one or more signal types from an input radio frequency (RF) signal. The fine-sensing modules may include a multiplier that combines an RF input signal and a delayed RF input signal to produce a correlation signal and an integrator that receives the correlation signal from the multiplier, where the integrator determines correlation values from integrating the correlation signal. The fine-sensing module also includes a comparator in communication with the integrator that compares the correlation values to one or more thresholds to generate information indicative of at least one signal feature of the RF input signal.

The spectrum-sensing cognitive radios include at least one antenna and a frequency-agile radio front-end module in communication with the at least one antenna and configured to transmit and receive radio frequency signals via the at least one antenna. In addition, a spectrum-sensing module, which may include one or both of coarse-sensing and fine-sensing modules, may be in communication with the at least one antenna and be configured to generate RF spectrum usage information.

    摘要： Embodiments of the invention may provide for a CMOS antenna switch, which may be referred to as a CMOS SPDT switch. The CMOS antenna switch may operate at a plurality of frequencies, perhaps around 900 MHz 1.9 GHz and 2.1 GHz according to an embodiment of the invention. The CMOS antenna switch may include both a receiver switch and a transmit switch. The receiver switch may utilize a multi-stack transistor with body substrate switching and source and body connection along with body floating technique to block high power signals from the transmit path by preventing channel formation of the device in OFF state as well as to maintain low insertion loss at the receiver path. Example embodiments of the CMOS antenna switch may provide for 35 dBm P 1 dB at both bands (e.g., 900 MHz and 1.9 GHz and 2.1 GHz). In addition, a −60 dBc second and third harmonic up to 28 dBm input power to the switch, may be obtained according to example embodiments of the invention.

    摘要： Embodiments of the invention may provide for a CMOS antenna switch, which may be referred to as a CMOS SP4T switch. The CMOS antenna switch may operate at a plurality of frequencies, perhaps around 900 MHz and 1.9 GHz according to an embodiment of the invention. The CMOS antenna switch may include both a receiver switch and a transmit switch. The receiver switch may utilize a multi-stack transistor with body substrate tuning to block high power signals from the transmit path as well as to maintain low insertion loss at the receiver path. On the other hand, in the transmit switch, a body substrate tuning technique may be applied to maintain high power delivery to the antenna. Example embodiments of the CMOS antenna switch may provide for 31 dBm P 1 dB at both bands (e.g., 900 MHz and 1.8 GHz). In addition, a 0.9 dB and −1.1 dB insertion loss at 900 MHz and 1.9 GHz, respectively, may be obtained according to example embodiments of the invention.
