Abstract A 33.6 ps LSB Time-to-Digital converter was designed in 130 nm BiCMOS technology. The core of the is a differential 9-stage ring oscillator, based on multi-path architecture. novel version this design proposed, along with an analytical model linearity. allowed us to understand source performance superiority (in terms linearity) our and predict further improvements. oscillator integrate...

A steganographic method called adjacent bin mapping (ABM) is presented. Firstly, it is applied to 3D geometries by mapping the coordinates within two adjacent bins for data embedding. When applied to digital images, it becomes a kind of LSB hiding, namely the LSB algorithm. In order to prevent the detection using a metric named histogram tail, the hiding is performed in a pseudorandom order. Th...

This study presents a simple method for high-hiding capacity. The basic concept uses a modulus operation. The proposed method has the following advantages: (1) the proposed method outperforms the simple LSB substitution method given the same range (0–m − 1) of data digits in the embedded data; (2) the proposed method achieves good image vision quality without the need for post-processing; (3) t...

In this paper a new configuration of up converter is presented. In this circuit, the LO and RF (LSB) frequencies are rejected thanks to a distributed and balanced circuit. Eight GaAs PHEMTs with a gate-length of 0.25 μm are used. A conversion gain of -6 dB and a rejection over 6 dB on LO and RF (LSB) are obtained.

So far, various components of image characteristics have been used for steganalysis, including the histogram characteristic function, adjacent colors distribution, and sample pair analysis. However, some certain steganography methods have been proposed that can thwart some analysis approaches through managing the embedding patterns. In this regard, the present paper is intended to introduce a n...

IMPORTANCE There are limited data on the use of the supraclavicular artery island flap (SCAIF) for parotid and lateral skull base (LSB) surgery. This flap can be an important reconstructive tool for these procedures. OBJECTIVE To describe the use of the SCAIF for parotid and LSB surgery and its success, as well as important technique modifications for successful use of the flap in this settin...

0 . 1 8 ~ CMOS process. The DAC is optimized for circuit calibration in large ASICs and occupies 0.01034 mm’ (1 IOW x 9 4 ~ ) of die area. Creative layout and current mirroring techniques are implemented to minimize area while providing output current with sufficient headroom. The measured DNLfiNL is better than 0.7/0.75 LSB and OH2 LSB for 1.8V and 1.4V power supplies, respectively. The DAC co...
