dc.description.abstract This paper presents design analysis and insights for a new continuous-time input pipeline (CTIP) analog-to-digital converter (ADC) architecture that has enhanced bandwidth. An all-pass filter-based analog delay in the signal path allows bandwidth extension to Nyquist signal bandwidths. A resetting integrator gain stage provides a signal path delay helping to increase the bandwidth while reducing the power cost. The noise filtering property of the resetting integrator gain stage preserves the medium resistive input benefit of CTIP ADCs. The resetting integrator allows the architecture to be implemented with a feedforward compensated op-amp using low-voltage CMOS processes. This paper has been verified by simulation results of a CTIP ADC with 1.2-V supply voltage designed in TSMC's 65-nm CMOS technology. en
