Scaling of CMOS technology has made major innovations in the last decade with the introduction of strained silicon and high-k metal gate, however at the same time an increasing amount of complex analog mixed-signal circuit functionality has been integrated on microprocessors and SOCs. Examples of the key analog mixed-signal circuit functional blocks implemented in advanced 45nm and 32nm logic CMOS...
A VCO is implemented in an RF 90nm CMOS process and covers the frequency range 2.55-4.08GHz. Drawing 19mA from 1.2V, the phase noise at 20MHz frequency offset from a 3.7GHz carrier is -156dBc/Hz, meeting the phase noise requirement for GSM. A second version of the VCO covers an additional 4.90-5.75GHz range, at the expense of a higher phase noise in the added band. In this way, all WCDMA/EDGE bands...
This paper describes the design and implementation of a low-cost and low-power receiver IC that houses triple-band Radio Frequency (RF) receivers, baseband demodulators, audio decoders, audio DACs, and memories in a compact 11 mm × 8 mm BGA 88-pin package. At 150-mW power consumption of DAB+ systems operation which includes from RF inputs to audio DAC outputs, this singlechip IC achieves the highest-integration...
A low power 77GHz receiver, suitable to be used in a FM-CW Automotive Radar has been designed using a 1P6M 65nm RFCMOS process. It has been implemented using a direct conversion architecture. The 77GHz signal generation block generates a FM-CW signal that pre-drives the external PA with a power level of -4.5dBm and also works as a Local Oscillator (LO) signal in the downconversion mixer. The ladder...
