Abstract:

Wide-band LNAs suffer from a fundamental trade-off between noise figure NF and source impedance matching, which limits NF to values typically above 3 dB. Some years ago, we proposed a feed-forward noise canceling technique to break this trade-off. This presentation reviews the principle of the technique and its key properties. Later, we realized that it is also possible to exploit the technique to cancel the distortion contribution of the matching device. In parallel, other research groups have also exploited the noise canceling technique. This presentation reviews various proposed circuits and the obtained results.
