This survey investigates recent “time interleaved analog to digital converters (TI-ADCs)” mismatches correction techniques. It includes each technique performance evaluation on the basis of SNDR, SFDR, Frequency and Input signal. Many algorithms have been developed over the past two decades, mainly emphasizing on the digital calibration of TIADCs mismatches. The aim of this survey is to review ...

A carrier phase-shifted (CPS) double sideband (DSB) modulation technique in radio-over-fiber (RoF) system is proposed and experimentally demonstrated. By tuning the biases in a single-drive dual parallel Mach-Zehnder modulator (SD-DPMZM), the optical carrier in the DSB spectrum acquires additional phase shift. The transmittance response of a dispersive RoF link is thus being controlled and shif...

An active filter with a 50 Ω buffer suitable as an anti-alias filter to drive a highly linear ADC is implemented in 0.13 μm SiGe BiCMOS. This 6th-order Chebyshev filter has a 3 dB cutoff frequency of 28.3 MHz and achieves 36.5 dBm OIP3. Nonlinear digital equalization further improves OIP3 to 43.6 dBm. Measurements show 92 dB of rejection at the stopband and a gain of 49 dB. The measured in-band...

A 4 order RF LC Σ∆ ADC clocked at 3.6GHz and centered at 900MHz is presented. The simplicity of the ADC architecture results in a significant performance enhancement and power consumption reduction. The ADC, suitable for Software Defined Radio applications, is implemented in a standard 130nm CMOS technology. It achieves a 52dB SFDR and a 50dB SNDR in a 28MHz BW and consumes only 15mW from a 1.2...

36 Imaging genetics is an emerging field in which the association between genes and neuroimaging37 based quantitative phenotypes are used to explore the functional role of genes in neuroanatomy and 38 neurophysiology in the context of healthy function and neuropsychiatric disorders. The main obstacle 39 for researchers in the field is the high dimensionality of the data in both the imaging phen...

A novel coherent optical receiver is proposed and experimentally demonstrated by using a feedback technique capable of reducing the nonlinear distortion in a traditional receiver while retaining the signal to noise ratio. ©2006 Optical Society of America OCIS codes: (060.1660) Coherent communications; (120.5060) Phase modulation

A new Successive-Approximation ADC (Analog-toDigital Converter) was designed which not only consumes little power, but also requires a small chip area. To achieve those goals, both comparator and internal DAC (Digital-to-Analog Converter) have been improved. The ADC was designed in a 1.2 μm CMOS double-poly double-metal n-well process. It performs 10-bit conversion with 67 dB SFDR. Power consum...
