IEEE VLSI研讨会：Imec推出覆盖5GHz的RF ADCsVLSI Symposium: RF ADCs cover 5GHz
1、在IEEE VLSI研讨会上，Imec展示了两种用于'超越5G'通信的ADC，一种用于基站，一种用于手机，两者均工作频率高达5GHz。2、基站ADC为10Gsample/s CMOS分层时间交错ADC，在低频时提供9 ENOB，在奈奎斯特频率时提供8.2 ENOB，功耗为350mW。3、手机ADC采用多比特流水线架构，配备后台校准，实现了10.91 ENOB和81dB SFDR，采样率为1Gsample/s时功耗仅为17.8mW。1. Imec unveiled two ADCs at the IEEE VLSI Symposium, designed for 'beyond 5G' communication, one for base stations and one for phones, both operating up to 5GHz. 2. The base station ADC is a 10Gsample/s CMOS hierarchical time-interleaved ADC with 9 ENOB at low frequencies and 8.2 ENOB at Nyquist, consuming 350mW. 3. The handset ADC uses a multi-bit pipelined architecture with background calibration, achieving 10.91 ENOB and 81dB SFDR at 1Gsample/s with 17.8mW consumption.
