In mixed-signal designs, substrate coupling of digital circuit noise can severely compromise the behavior of sensitive analog circuits. Proper characterization of substrate noise is therefore indispensable. In this paper, we present an experimental setup for the characterization of directly coupled substrate noise in bulk-type CMOS. We have integrated configurable substrate noise generation and...

this paper presents a design of an uwb downconversion integrated cmos resistive ring mixer with linear voltage regulator (lvr), to supply required biasing voltages for the mixer section. the designed mixer circuit has been optimized for using in heart rate extraction system with microwave doppler radar at 2.4ghz frequency. this mixer needs 2 dc bias voltages equal to 0.5 and 1 volts for its bes...

Methods applicable to teaching microelectronics at the undergraduate and graduate level in conjunction with an industrial fabrication capability are presented. Results of three semesters of teaching microelectronics at the graduate level with emphasis on both digital and analog circuits are summarized. Plans for teaching an undergraduate course utilizing the fabrication of integrated circuits a...

Continued scaling of CMOS technology affects both, the parameters and the characteristics of MOSFET and the integrated circuit built on them and introduces some new problems in analog design. The reduction of the gate length and the gate oxide thickness led to improvements in terms of chip area, speed and power consumption. At the same time, nonlinear output conductance, reduced voltage gain an...

Current mirror (CM) is the basic building block in analog and mixed mode circuit design. For high performance analog circuit applications, the current transfer ratio, output impedance and output swing are the most important parameters to determine the performance of the current mirror. CM’s are important for analog integrated circuits because of their wide use as constant sources or active load...

− This paper describes an analogue processing element (APE) suitable for high-density image sensor/processor array integrated circuits. The design tradeoffs between area, power consumption, speed and accuracy are discussed and the architecture of the APE is presented. The design follows a switched-current “analogue microprocessor” approach while the implementation of arithmetic operations is si...

-This paper describes the realization of a fuzzy controller which implements the simplified inference mechanism. CMOS analog circuits where signals are represented as currents are employed. However, the whole system is externally communicated through voltages, thus enabling simple interface with conventional control circuitry.
