Emerging Analog Filtering Techniques
21. Juni 2017 | Vortrag
Abstract: This talk will introduce three different techniques tailored to the implementation of channel selection filters in wireless transceivers: adaptive analog filters, filtering ADC and passive switched capacitor circuits.
The adaptive filters presented succeed to shape the filtering profile as function of the operative scenario without the need of any control loop. This allows to optimize the filter design by minimizing the average power consumption instead of the peak-dissipation occurred in the worst-case scenario, which has a very low probability to appear.
In the second part of the talk, a filtering ADC is presented. Although the interferes are suppressed before the analog to digital conversion, the filter profile is entirely defined in digital domain through a re-configurable filter able to track and suppress unwanted interferers.
The talk ends with a discussion on passive switched capacitors filters. A new intuitive continuous-time model will be introduced. The model easily allows to design high-order topologies even with complex conjugates poles without the need of any active device.
Measurements results on three different prototypes will be provided.
