Now a day’s demand of portable devices like multimedia devices, cellular phones, etc. are increasing and we are approaching towards handheld devices which are small in size and which requires large battery life. Power consumption has become most important design factor for VLSI circuits and system in low power devices. The Level shifter plays very critical role in low power devices. Level shift...

Substrate noise generated by digital circuits on mixed-signal ICs can disturb the sensitiveanalog/RF circuits, such as Low Noise Amplifier (LNA), sharing the same substrate. This paperinvestigates the adverse impact of the substrate noise on a high frequency cascode LNA laid out on alightly doped substrate. By studying the major noise coupling mechanisms, a new and efficientmodeling method is p...

A complete procedure for the design of W-band low noise amplifier in MMIC technology is presented. The design is based on a simultaneously power and noise matched technique. For implementing the method, scalable bilateral transistor model parameters should be first extracted. The model is also used for transmission line utilized in the amplifier circuit. In the presented method, input/output ma...

Mixed and analog systems design with high performance suffers from many difficulties due to supply voltage, power consumption and area overhead. A need for low-voltage low-power operational amplifiers exists and used for some applications. This paper deals an effective OTA design for good PSRR, low-voltage, low-power and wide output voltage swing operational amplifier. Trying to combine an alte...
