Noise Canceling

This paper presents a power-efficient noise-canceling technique based on the feed-forward amplifiers, considering a fundamental tradeoff between noise figure (NF) and power consumption in the design of wide-band amplifiers. By suppressing the input signal of the noise cancellation amplifier, the nonlinear effect on the amplifier can be reduced, as well as the power consumption can be smaller. Furthermore, as a lower gain of the noise-canceling sub-amplifier can be achieved simultaneously, further reduction of the power consumption becomes possible. The verification of the proposed technique is conducted with Spectre simulation using 90nm CMOS process.

Main Path

This paper presents an N-path filter with high out-of-band rejection using feed-forward technique. The structure utilizes two four-path filters, one as the main-path and the other as auxiliary-path, and two TIAs to increase the order of the filter from two to four. As a result of this, and due to using two series resistors in the main path, the out-of-band rejection is significantly improved. Analysis and simulations show that the series resistors can be chosen such that the NF degradation is below 2[Formula: see text]dB while the out-of-band rejection is improved by about 20[Formula: see text]dB. Therefore, the trade-off between the insertion-loss and out-of-band rejection is relaxed compared to conventional N-path filter. Also, it is shown that decreasing the size of baseband capacitors improves the NF of the filter. The effect of clock phase-noise on NF of the filter in the presence of strong out-of-band blocker is modeled and simulated.
