Design Considerations for a Direct RF Sampling Mixer

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....
