Analog Active Noise Canceling Headset
Analog systems to achieve active noise cancellation in headphones were designed and implemented. Our project addresses two distinct technqiues feed forward and feedback systems. The work up to mid-semester, which was focused mainly on a feed-forward system with the motivation of developing a clip-on platform for generic earphones, is presented briefly. Limitations of this approach that lead to ...

متن کاملThermal Noise Canceling in LNAs: A Review
Most wide-band amplifiers suffer from a fundamental trade-off between noise figure NF and source impedance matching, which limits NF to values typically above 3dB. Recently, a feed-forward noise canceling technique has been proposed to break this trade-off. This paper reviews the principle of the technique and its key properties. Although the technique has been applied to wideband CMOS LNAs, it...
متن کاملA Transformer Noise-Canceling Ultra-Wideband CMOS Low-Noise Amplifier
Previously reported wideband CMOS low-noise amplifiers (LNAs) have difficulty in achieving both wideband input impedance matching and low noise performance at low power consumption and low supply voltage. We present a transformer noise-canceling wideband CMOS LNA based on a common-gate topology. The transformer, composed of the input and shunt-peaking inductors, partly cancels the noise origina...
متن کاملActive Noise Canceling Using Analog Neuro-Chip with On-Chip Learning Capability
A modular analogue neuro-chip set with on-chip learning capability is developed for active noise canceling. The analogue neuro-chip set incorporates the error backpropagation learning rule for practical applications, and allows pin-to-pin interconnections for multi-chip boards. The developed neuro-board demonstrated active noise canceling without any digital signal processor. Multi-path fading ...
