Assessment of Mandibular Anterior Nutrient Canals in Patients with and without Periodontal Disease Open
Background: Nutrient canals (NCs) are radiolucencies in the bone that transit blood vessels and nerves. Aim: To use cone beam computed tomography (CBCT) to assess the incidence, diameter, and location of NC in healthy and periodontal disea…

Design of High-Speed Time-Interleaved Delta-Sigma D/A Converters Open
Digital-to-analog (D/A) converters (or DACs) are one the fundamental building blocks of wireless transmitters. In order to support the increasing demand for highdata-ate communication, a large bandwidth is required from the DAC. With the a…

An 11 GS/s 1.1 GHz Bandwidth Interleaved ΔΣ DAC for 60 GHz Radio in 65 nm CMOS Open
This work presents an 11 GS/s 1.1 GHz bandwidth interleaved ΔΣ DAC in 65 nm CMOS for the 60 GHz radio baseband. The high sample rate is achieved by using a two-channel interleaved MASH 1–1 architecture with a 4 bit output resulting in a pr…

Effect of Clock Duty-Cycle Error on Two-Channel Interleaved DACs Open
Time-interleaved delta-sigma (Delta Sigma) modulation digital-to-analog converters (TIDSM DACs) have the potential for a wideband operation. The performance of a two-channel interleaved Delta Sigma DAC is very sensitive to the duty cycle o…
