摘要
This paper proposes the reconfigurable RX analog baseband transformer that supports multi-standard applications. The proposed ABB can transform its structure between a delta-sigma modulated ADC for narrow band and a baseband LPF for wide band with a simple switch configuration without extra cost. Thus, the ABB obtains efficiency in both size and power aspects. It occupies only 0.11mm(2) of active area by avoiding large capacitor for narrow band filtering and consumes 1.33mW and 12.1mW in GSM and LTE40M modes, respectively.
