Abstract

Depletion-mode CNTFETs are being fabricated successfully with useable tolerances and compact models are now available for circuit design and engineering. This paper presents the first design study of mixers based on those devices. The impact of peculiar device features and parasitic on analog and RF circuits is discussed in detail and the cascode mixer is selected to overcome challenges specific to the available technology. Circuit performance and design for operation in the 2.4 GHz IMS band are described in detail: while consuming 182 mW and driven with -2 dBm LO power, the mixer provides 8 dB conversion gain to a 10 MHz IF frequency.
