Modeling of Substrate Noise Impact on a Single-Ended Cascode LNA in a Lightly Doped Substrate (RESEARCH NOTE)
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...
متن کاملSubstrate Noise Reduction in CMOS Transistors: a methodology definition
Substrate coupling can corrupt low level analog signals and impair the performance of monolithic integrated circuits. Therefore, a characterization methodology able to evaluate the efficiency of the countermeasures against crosstalk, appears very important for designers. In this paper, after the verification that PMOS transistors are more sensitive to substrate voltage fluctuations than NMOS on...
متن کاملSwitched-Current Cells in Standard CMOS Process
The minimum supply voltage €or a typical switched-current (SI) cell can be shown to be greater than 2 v ~ + 2VDssat approximately due to the fact that an additional voltage drop is required for the MOS switch, which is connected to the gate of the memory transistor. Thus, a minimum supply voltage of 1.5 V is usually required in a standard CMOS process. In this paper, an active switching scheme ...
متن کاملIntroduction to Substrate Noise in Soi Cmos Integrated Circuits
In this paper an introduction to substrate noise in silicon on insulator (SOI) is given. Differences between substrate noise coupling in conventional bulk CMOS and SOI CMOS are discussed and analyzed by simulations. The efficiency of common substrate noise reduction methods are also analyzed. Simulation results show that the advantage of the substrate isolation in SOI is only valid up to a freq...
متن کاملNoise in single quantum well infrared photodetectors
The noise of the dark current and photocurrent is an important factor in operation of the quantum well infrared photodetectors ~QWIPs!. For typical operating conditions, the main source of fluctuations in QWIPs is generationrecombination noise associated with the excitation of carriers from the QWs into the continuum and their capture into the QWs. For applications the study of noise in QWIPs i...
