This paper considers the implementation of a continuous-time low-pass single-bit ΔΣ analog-digital converter (ADC) for radar applications. By taking advantage of the high transit frequency of a 0.25μm SiGe BiCMOS technology, the 3rd-order modulator operates at 1.92GHz and achieves 77.8dB SNDR within a bandwidth of 15MHz, when simulating the sensitive circuit parts on transistor level. Thanks to the inherent linearity of single-bit digital-analog converter (DAC), high linearity of 90dB spurious-free dynamic range (SFDR) can be achieved.
