摘要

In this paper, a broadband, inductorless noise-canceling low-noise transconductance amplifier is presented. The proposed circuit is suitable for TV White-Space applications. It has a single-ended input, eliminating the need for an external balun, and a balanced output, which can be followed by a double-balanced current-switching mixer for high IIP2. The circuit is based on a common-gate stage with a feed-forward noise-canceling common-source path. High common-source transconductance improves noise but leads to unbalanced output currents. The currents are re-balanced with the help of a current multiplier, which introduces much less noise than a classic current mirror. The power consumption is only 3 mW, for a NF<;2.6 dB and a good input matching (S<; -20 dB) from 100 MHz to 1GHz.
