A dual-band fully integrated transceiver for IEEE 802.11a/b/g/j/n WLAN was implemented using 0.13nm CMOS technology. The proposed hybrid up/down-conversion architecture, which is mixed double- and direct-conversion, was employed in 5GHz and 2.4GHz bands, respectively, in order to eliminate the needs for high LO frequency generations. The hybrid up/down conversion transceiver was archived with small...
A miniature CMOS monolithic stacked spiral inductors were implemented by using a standard 0.13 mum one-poly-eight-metal (1P8M) Radio Frequency (RF) CMOS technology. The proposed taper geometry for enhanced quality factor (Q-factor) and the stacking technique for size reduction were employed. According to the measurement results, the proposed inductors are only 8% size occupation of the conventional...
Ultrawideband communications using impulse signal is recently one of the key technologies for wireless communications due to its feasibility to various applications. Ultra wideband (UWB) RF chaotic system, a modified UWB system, using noise-like signal has advantageous features including low power consumption, efficient power management, compactness, and robustness in multipath and thus lower price...
