Design considerations for a direct RF sampling mixer
IEEE Transactions on Circuits and Systems II: Express Briefs , Volume 54 - Issue 11 p. 934- 938
This brief presents a detailed time-domain and frequency-domain analysis of a direct RF sampling mixer. Design considerations such as incomplete charge sharing and large signal nonlinearity are addressed. An accurate frequency-domain transfer function is derived. Estimation of noise figure is given. The analysis applies to the design of sub-sampling mixers that have become important for software-defined radio and analog-to-digital converter.
