|Title||A Novel Two-Channel Continuous-Time Time-Interleaved 3rd-order Sigma-Delta Modulator with Integrator-Sharing Topology|
|Authors||Talebzadeh, J. and Kale, I.|
this paper presents a 3rd-order two-path Continuous-Time Time-Interleaved (CTTI) delta-sigma modulator which is implemented in standard 90nm CMOS technology. The architecture uses a novel method to resolve the delayless feedback path issue arising from the sharing of integrators between paths. The clock frequency of the modulator is 320MHz but integrators, quantizers and DACs operate at 160MHz. The modulator achieves a dynamic range of 12 bits over a bandwidth of 10MHz and dissipates only 28mW of power from a 1.8-V supply.
