Abstract
A broadband, inductorless receiver including a noise-canceling low-noise transconductance amplifier (LNTA), suitable for TV White-Space applications is presented. The LNTA has single-ended input and balanced output, allowing double-balanced mixing for high IIP2. The circuit consists of 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, re-balanced with a low-noise current multiplier. A self-calibrating loop boosts the IIP2 above 52 dBm across process corners. The LNTA bandwidth is from 100â¯MHz to 1â¯GHz. Power consumption is only 3â¯mW for a NFâ¯<â¯2.6â¯dB and an IIP3 of 1 dBm.
