A reconfigurable low-pass/high-pass \(\varDelta \varSigma\) ADC suited for a zero-IF/low-IF receiver
This paper presents the design of a reconfigurable delta sigma analog to digital converter. Its main degree of freedom is the choice of the noise sha** between low-pass and high-pass. Thanks to this reconfig...

A 1.44-mW, 1-MHz bandwidth continuous-time Σ∆ modulator with 10-bit ENOB in 130-nm CMOS
A low-power, low-pass continuous-time sigma-delta A/D modulator with 1-MHz bandwidth is implemented in a 130-nm CMOS process. The circuit is targeted for an IEEE 802.15.4 direct conversion receiver operating i...
