This work describes the design of a 16 point analog domain FFT using a Charge Re-use Analog Fourier Transform (CRAFT) engine. The circuit relies on charge re-use to achieve 47 dB average output SNDR on an instantaneous input bandwidth of 5 GHz, and consumes only 3.8 mW (12.2 pJ/conv.). The CRAFT engine is used as a wide-band, low power RF front-end channelizer for software defined radio (SDR) applications. The paper also discusses the handling of circuit non-idealities for the CRAFT design: their significance, modeling, and circuit techniques for their mitigation. These techniques enable this implementation to achieve a large dynamic range even at high speeds.
