Abstract
A high resolution time-to-digital converter (TDC) architecture is proposed. The architecture combines the principles of noise-shaping quantization and charge-pump to build a third-order ΔΣ TDC with a dedicated feedback DAC. Fabricated in a 0.13μm CMOS process, the prototype TDC achieves better than 71dB DR and 67dB SNDR in 2.81MHz signal bandwidth (OSR=16) and consumes 2.58mW.
