Abstract :
A new architecture for IF to RF conversion is presented. The architecture is based on a tunable continuous-time bandpass ΣΔ modulator with fractional delay in combination with a Manchester coder and decoder. The suitability of the proposed architecture is discussed in the context of a software-defined radio. Mixed-signal behavioural simulations confirm the validity of the concept.
