A DC-to-1 GHz Tunable RF \Delta \Sigma ADC Achieving DR = 74 dB and BW = 150 MHz at f = 450 MHz Using 550 mW
A sixth-order dc-to-1 GHz tunable continuous-time lowpass/bandpass ΔΣ ADC in 65-nm CMOS targeting RF and IF digitizing applications is presented. The ADC achieves 150-MHz bandwidth at 450-MHz center frequency with 74-dB dynamic range at 4-GHz sampling frequency while consuming 550 mW. This performan...

| description | A sixth-order dc-to-1 GHz tunable continuous-time lowpass/bandpass ΔΣ ADC in 65-nm CMOS targeting RF and IF digitizing applications is presented. The ADC achieves 150-MHz bandwidth at 450-MHz center frequency with 74-dB dynamic range at 4-GHz sampling frequency while consuming 550 mW. This performance is enabled by a reconfigurable LC and active-RC modulator structure, fifth-order and seventh-order feedforward operational amplifiers, a self-cut-off comparator, and a dual-supply DAC. |
