Low Phase Noise

This paper presents the design, simulation, and measurements of a low power, low phase noise 10.25–11.78 GHz LC digitally controlled oscillator (LC DCO) with extended true single phase clock (E-TSPC) frequency divider in 130 nm complementary metal–oxide–semiconductor (CMOS) technology for 5G intelligent transport systems. The main goal of this work was to design the LC DCO using a mature and low-cost 130 nm CMOS technology. The designed integrated circuit (IC) consisted of two parts: the LC DCO frequency generation and division circuit and an independent frequency divider testing circuit. The proposed LC DCO consisted of the following main blocks: the high Q-factor inductor, switched-capacitors block, cross-coupled transistors, and the current control block. Inductors with switched-capacitors block formed an LC tank. The designed E-TSPC frequency divider consisted of eight blocks connected in a series; each block increased the division ratio by a factor of two. The frequency of the input signal was divided in the region from two to 256 times using the designed divider. The main parameters of the designed E-TSPC divider and the LC DCO measurements were given as follows: LC DCO achieved a wide tuning range from 10.25 GHz to 11.78 GHz (1.53 GHz, 15.28% bandwidth); phase noise at 1 MHz offset frequency from LC DCO lowest carrier frequency was −113.42 dBc/Hz; phase noise at 1 MHz offset frequency from LC DCO highest carrier frequency was −110.51 dBc/Hz; The average power consumption of the designed LC DCO core and E-TSPC divider were 10.02 mW and 97.52 mW, respectively; the figure of merit (FOM) and the extended FOMT values of the proposed LC DCO were −183.52 dBc/Hz and −187.20 dBc/Hz, respectively. These FOM and FOMT results were achieved due to very low phase noise (−113.52 dBc/Hz) and a wide frequency tuning range (15.28%). The total layout area including the pads was 1.5 mm × 1.5 mm, with the largest part of the layout occupied by the proposed LC DCO (193 µm × 311 µm). The largest part of the LC DCO was occupied by the inductor 184 µm × 184 µm. The manufactured chip was packed into a quad flat no-leads (QFN) 20 pads package.

The City

This innovative book examines the development of modernism in four European cities: London, Paris, Berlin, and Vienna. Focusing upon how literary and cultural outsiders represented various spaces in these cities, it draws upon contemporary theories of affect, mood, and literary geography to offer an original account of the geographical emotions of modernism. It considers three broad features of urban modernism: the built environment of the particular cities, such as cafés or transport systems; the cultural institutions of publishing that underpinned the development of modernism in these locations; and the complex perceptions of writers and artists who were outsiders to the four cities. Particular attention is thus given to the transnational qualities of modernism by examining figures whose view of the cities considered is that of migrants, exiles, or strangers. The writers and artists discussed include Mulk Raj Anand, Gwendolyn Bennett, Bryher, Blaise Cendrars, Joseph Conrad, T. S. Eliot, Christopher Isherwood, Hope Mirlees, Noami Mitchison, Jean Rhys, Sam Selon, and Stephen Spender.
