Polyphase-FFT (P-FFT) techniques allow for low power implementations of high performance multi-channel filter banks by utilizing computation sharing like a standard fast Fourier transform (FFT). Additionally, it enables a longer “effective window l

This paper presents a prototype analog 4-channel-I/Q polyphase-FFT filter bank (PFFB) using passive switched capacitor circuits to channelize wideband signals. Like FFTs, the proposed PFFB shares computations for low power. The PFFB allows for a long

In this paper, the relationship between the bandwidth (BW) and power efficiency of a source follower based (SFB) filter is quantitatively analyzed, and a design methodology for a SFB filter for optimized BW - power consumption is introduced. The prop
