This paper presents a fully integrated low power and low phase-noise VCO, having a tuning range over one octave (1.2 GHz to 2.5 GHz). The architecture is fully differential and the differential tuning offers a common-mode rejection of 31 dB. The VCO is implemented in a 0.18μm CMOS process using a 1.8 V supply. The circuit, including the bias, consumes only 11.6 mW at 1.2 GHz oscillation frequency, the phase-noise is -129 dBc/Hz at 1 MHz frequency offset.

Conference Paper: A DVB-H receiver architecture[Show abstract] [Hide abstract]
ABSTRACT: This paper proposes an integrated DVB-H receiver architecture. The main focus has been low power consumption, aiming at handheld battery operated devices. The total power consumption for the RF tuner is estimated to be less than 20 mW with a duty cycle of 10%. The receiver uses a low-IF architecture and cover the receive bands from 470 MHz to 702 MHz, with an IF of 4.57 MHz. The proposed receiver meets the DVB-H requirements. The sensitivity is -88 dBm, the noise figure 5.7 dB and the adjacent channel protection ratio (ACPR) is -51 dB.NORCHIP Conference, 2005. 23rd; 12/2005
