“…The sensitivity performance of our E-EDGE solution lies in a competitive range and shows better sensitivity than [20], [1], [21]. Our system shows a sensitivity of 1.2 dB below the transceiver of [22], which reports a sensitivity of 113 dBm (Class II RBER) and is based on a noise figure of 2.4 dB, while our RF-IC has a noise figure of 4 dB [17] including front-end insertion loss.

In this paper, a baseband ASIC which supports receive diversity and soft-output Viterbi equalization for enhanced 2G networks is presented. It includes a transmitter and receiver with a symbol detector and a decoder with a dedicated incremental redundancy implementation, as well as the necessary control capability to autonomously communicate with the RF-IC. The ASIC is connected to an RF-IC to build a complete Evolved EDGE transceiver system. The transceiver system reaches a measured sensitivity close to 112 dBm for single-antenna GSM voice channels and achieves the reference interference performance for adjacent channels 11.4 dB above 3GPP requirements. It is the first reported solution which fulfills the most demanding 3GPP Downlink Advanced Receive Performance Phase 2 testcases specified for Rx-diversity. The ASIC occupies 6 mm in 130 nm CMOS with a power consumption between 3.9 and 14 mW.Index Terms-Baseband ASIC, enhanced 2G networks, evolved EDGE (E-EDGE), evolved EDGE testbed, GSM/EDGE, hybrid ARQ, incremental redundancy, interference cancellation, internet of things (IoT), machine-to-machine (M2M), Rx diversity, space-time processing.

“…On the other hand, switched regulators exhibit higher efficiency; however, more on -chip area for the more complex switching stage, one more off -chip power inductor, higher voltage ripple, and electromagnetic interference (EMI) can cause problems. Moreover, additional noise -reduction fi ltering has to be utilized to suppress the spurious switching in the receive and transmit band for the RF part [80] . In order to assess the two architectures, the achievable current consumption and implementation costs are evaluated.…”

“…With an ever-increasing number of mobile devices in common use, the efficient use of power is an important issue [1][2][3][4][5][6][7]. In particular, many techniques have been studied to improve power efficiency when such devices are in stand-by mode, since they operate in this mode most of the time [8].…”

This letter proposes a new adaptive on-time pulse-frequency modulation (PFM) circuit that operates at a wide range of supply voltage levels and that can generate various output voltage levels compared to conventional circuits. The circuit's peak inductor current is well-controlled; the magnitude of the output ripple voltage is constant, even when the supply and output voltage levels are significantly different. Since the ripple voltage is a noise component, constant ripple voltage is important for predictable noise of a power management system.
