The presentation will provide insight into the development of building blocks required in broadband CMOS direct-conversion receivers realized in deep submicron CMOS technologies. Dr. Silva-Martinez will describe several techniques used within the front end amplifier, mixer design and baseband transimpedance amplifier to improve both Noise Figure and linearity of the receiver chain. For example, improved robustness to out-of-band interference and outstanding linearity are obtained by employing a broadband common-gate (CG) low-noise transconductance amplifier (LNTA) with dual feedback to improve both gain and noise figure (NF) without breaking the fixed relationship between input impedance, transconductance gain, and load impedance. The core of the most recently reported receiver in IEEE-JSSC (RF and baseband signal path) consumes only 13 mW, and the prototype receiver achieves over 22.4dB conversion gain, 7 dB NF, and over -1.5 dBm IIP3 from 1.4 to 5.2 GHz. Dr. Silva-Martinez will also discuss the design of a couple of highly linear broadband LNAs whose 1dB compression point is over 0dBm. Other relevant building blocks such as Power management circuits (LDOs), Quadrature Frequency synthesizers and broadband ADCs will be briefly discussed as well.
