This paper deals with the ultra low-voltage design and application of an inverter-based driver. In order to ensure a reliable value of the overdrive voltage for transistors, the topology based on a boosting technique was used. The driver was designed in 130nm CMOS technology and verified by simulations including technology corners and measurement of prototyped chips. The whole boosted driver achieves...
This work deals with the influence of increasing rate of integration (i.e. technology downscale) on the main parameters of integrated circuits. Our concerns are focused on calibration methods of analog integrated circuits that can compensate undesired side effects of technology downscale. The paper describes both the general principle of calibration system as well as design requirements for main blocks...
This paper presents design of the inverter-based driver for low-voltage applications, with topology for boosting the transistors overdrive voltage. The proposed driver topology was designed through detailed circuit analysis and optimization, and it is suitable for use in a switched capacitor charge pump. The driver was designed in 130 nm CMOS technology and verified by simulations including technology...
The paper deals with design and analysis of a variable-gain amplifier (VGA) working with a very low supply voltage, which is targeted for low-power applications. The proposed amplifier was designed using the bulk-driven approach, which is suitable for ultra-low voltage circuits. Since the power supply voltage is less than 0.6 V, there is no risk of latchup that is usually the main drawback of bulk-driven...
Design of variable-gain amplifier (VGA), based on fully differential operational amplifier is presented. The proposed VGA topology was verified through simulations and analysis of main circuit parameters. The VGA is designed in 0.35 μm CMOS technology using Cadence environment and BSIM3 family of models. Designed circuit works with the power supply of 3.3 V. The simulation results show that gain bandwidth...
