SYSTEM AND METHOD FOR PROVIDING A CARBON NANOTUBE MIXER

摘要

An embodiment of a system and method provides a carbon nanotube transistor (CNT) mixer with a low local oscillator power requirement and no inter-modulation products. Specifically, an embodiment of the system and method provides two kinds of device current-voltage (I-V) characteristics on the same integrated circuit: exponential and linear. The CNT I-V characteristics support both the ideal exponential control characteristic (determined by physics constants) and the ideal linear control characteristic (also determined by physics constants), resulting in an ideal multiplier. In other words, the CNT mixer is mathematically equivalent to an ideal multiplier. Such an ideal multiplier can be used as a mixer with low local oscillator power requirement and virtually no inter-modulation products.
