This paper describes the use of very high precision noise shaping sigma delta modulation techniques for high fidelity audio applications that require a signal-to-noise ratio (SNR) of at least +80 dB. This paper discusses the implementation of a fifth-order sigma delta modulator with an oversampling frequency of 5.68 MHz. Specifically this paper is a comparative study of Matlab and Pspice implementations of our fifth order sigma delta modulator with a VHDL-based finite impulse response (FIR) filter.
