A novel high speed and tunable transconductor suitable for analog and mixed-signal fuzzy circuits operating in current mode and a high linear MIN circuit are proposed. Using this OTA, we construct are high speed Gaussian and trapezoidal-shaped fuzzifier and implement S-shaped and Z-shaped function with all parameters (slop, width, and position) independently and continuously tunable, and excellent...
In this work, the bulk-gate controlled circuit to improve the power supply ripple ratio (PSRR) of a Low Dropout Regulator (LDO) which deteriorates due to lowering power consumption is proposed. Designing with 0.25 mum CMOS process, the simulation results by HSPICE shown that the proposed circuit provides a high performance of PSRR even though 1/10 of the power consumption is reduced compare to the...
A delay-locked loop of multi-band selector with wide-locking range and low power dissipation is presented. The architecture of the proposed delay-locked loop consists of phase frequency detector, charge pump, band selector, multi-control delay line, and start-up circuit. The multi-band selector is used to extend operation frequency of delay-locked loop by switching the multi-control delay line. The...
Plasma-exposed Si surface related to Si recess in source/drain region was investigated in detail for various superposed bias configurations with frequencies of 13.56 MHz and 400 kHz. Two different bias powers were utilized by an inductively coupled plasma reactor (ICP). The surface layer (SL) and the interfacial layer between the SL and Si substrate (IL) were analyzed by spectroscopic ellipsometry...
