Abstract
The bandwidth of the RF amplifier severely limits the use of gain-boosted N-path receivers at high frequencies. Apart from limitation on the achievable impedance matching, the noise figure degradation severely handicaps the performance of the receiver. This paper describes a linear periodically time-variant (LPTV) analysis of the gain-boosted N-path receiver taking the amplifier bandwidth into consideration. By using the proposed analysis, the gain-boosted N-path receiver performance degradations are quantified and explained.
