In the Orthogonal Frequency-Division Multiplexing (OFDM) based transceivers, digital computation of the Discrete Fourier Transform (DFT) is a power hungry process. Reduction in the hardware cost and power consumption is possible by implementing the DFT processor with analogue circuits. This thesis presents the real-time recursive DFT processor. Previously, changing the transform length and scaling the power could only be performed by digital Fast Fourier Transform (FFT) processors. By using the real-time recursive DFT processor, the decimation filter is eliminated. Thus, further reduction in the hardware cost and power consumption of the multi-standard transceiver is achieved. The real-time recursive DFT processor was designed in 180 nm CMOS technology. Results of device mismatch analysis indicate that the 8-point recursive DFT processor has a yield of 97.5% for the BPSK modulated signal. For the QPSK modulated signal, however, yield of the 8-point recursive DFT processor is 8.9%. Moreover, doubling the transform length reduces the average dynamic range by 3dB. Accordingly, the 16-point recursive DFT processor has a yield of 43.4% for the BPSK modulated signal. Power consumption of the recursive DFT processor is about 1/6 of the power consumption of a previous analogue FFT processor.
