A continuous-time ΣΔ ADC based on TDLTE terminals is implemented with 0.13 μm CMOS process to address the power consumption issue of TD-LTE terminals. The low-pass filter in conventional receiver is removed to save power consumption by using the proposed ADC. The proposed ADC is with 3
rd
loop filter
3 bit quantizer
and compensates excess loop delay (ELD) in a compact way. The test results show the ADC achieves 66 dB dynamic range in TDLTE 20 MHz bandwidth
