A novel MASH delta-sigma (ΔΣ) ADC architecture is introduced that has a multirated voltage controlled oscillator (VCO)-based ADC in its second stage. The architecture allows for low power and high speed operation and is insensitive to the VCO linearity. A prototype consists of a first-order switched-capacitor (SC) modulator operating at 100 MHz in the first stage followed by a second-stage VCO-based ADC operating at 1.2 GHz. A custom IC prototype of this architecture achieves 77.3 dB signal-to-noise-ratio (SNR) over a 4 MHz signal bandwidth with a power consumption of 13.8 mW. It was fabricated in a 130 nm 1P8M CMOS process. The resulting FoM is 298 fJ per conversion.
