A low power dual band fully integrated receiver incorporating IEEE 802.11a/b/g/n WLAN standards was manufactured using 0.13μm CMOS technology. In this paper, the proposed hybrid mixer, which uses both double- and direct-conversion architecture, operates in the 5GHz band in order to eliminate the need for high LO frequency generators. This hybrid mixer is a small low power device that shares...
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...

In this paper, an accurate temperature sensor was implemented using 0.18 mum CMOS technology. The temperature sensor which was designed with the bandgap reference circuit is calibrated by trimming common mode voltage of an operational amplifier. The temperature sensor can compensate for other blocks of the IC chip above the special temperature when the ADC was a power off for low power operation....
A design of a CMOS bandgap voltage reference and reference current generator is described and the measurement results are presented in wide temperature range. Using by the resistive subdivision method, the reference circuit is operated with low supply. The measured reference voltage is 630 mV and temperature coefficient of bandgap reference is 29 ppm/??C from -10??C to 100??C with 1.2 V supply voltage...
