A single-chip quad-band GSM/GPRS transceiver in 0.18μm standard CMOS

Abstract: CMOS RF has evolved from a novelty to a necessity with the mergence of all analog and digital functionality into a single chip for standards such as Bluetooth and WLAN/802.11. The stringent performance requirements associated with cellular standards such as GSM, however, has either limited the level of RF transceiver integration, or compelled the use of alternative technologies such as BiCMOS or bipolar [1]. In this paper, a fully integrated quad-band GSM/GPRS transceiver, fabricated in a 0.18µm CMOS process, … Show more

“…The passband gain is about 23 dB, and the noise figure is 3.9 dB. Even though this is higher than what is typically achieved [7], it is still advantageous once the 3-dB loss of the SAW filter and the switch is included. The LNA is tuned to 1.96 GHz and has a measured 3-dB bandwidth of about 250 MHz, set primarily by the output inductor, which has a Q value of about 8.…”

“…Third, the presence of these filters removes the flexibility of sharing the LNAs in multi-mode or multi-band applications, particularly in software-defined radios. Therefore, it is highly desirable to eliminate these external filters.Unlike the receiver, the GSM transmitter does not suffer from similar issues, thanks primarily to the translational loop, or PLL-based architecture [3][4][5][6][7][8]. The narrow PLL bandwidth typically makes the VCO the only contributor at far-out offset frequencies, and typically, by proper design, the noise and spur requirements are met.…”

“…When more and more RF building blocks can be realized in silicon technologies, such as Bipolar or CMOS; the natural evolution is to integrate them onto the same silicon die. There are many early examples of transceiver integrations, some notable ones are listed here [4][5][6] [7]. The main challenge in transceiver integration is to minimize couplings between building blocks.…”

“…These data meet the performance requirements of the GSM standard and comparable to the recent GSM receivers realized in the CMOS process using the low-IF architecture [7]. The developed NPN BJTs are also applied to realize high IP3 and low NF for DVB-H tuner [8].…”
