A Multiproject Chip Approach to the Teaching of Analog MOS LSI and VLSI

Multiproject chip implementation has been used in teaching analog MOS circuit design. After having worked with computer simulation and layout aids in homework problems, students designed novel circuits including several high performance op amps, an A/D converter, a switched capacitor filter, a 1 K dynamic RAM, and a variety of less conventional MOS circuits such as a VII converter, an AC/DC converter, an AM radio receiver, a digitally-controlled analog signal processor, and on-chip circuitry for measuring transistor capacitances. These circuits were laid out as part of an NMOS multiproject chip. Several of the designs exhibit a considerable degree of innovation; fabrication pending, computer simulation shows that some may be pushing the state of the art. Several designs are of interest to digital designers; in fact, the course has provided knowledge and technique needed for detailed digital circuit design at the gate level

A Divide and Conquer Technique for Implementing Wide Dynamic Range Continuous-Time Filters

This paper presents a technique for implementing analog filters with wide dynamic range and low power dissipation and chip area. The desired dynamic range of the filter is divided into subranges, each covered by a different filtering path optimized specifically for this subrange. This results in small admittance levels for the individual filtering paths and correspondingly small power dissipation and chip area. The system provides undisturbed output during range switching, contrary to conventional automatic gain control (AGC)/filter arrangements that generate disturbances every time the gain of the AGC changes. We also report on a low-noise highly linear CMOS transconductor useful for high-frequency applications. A chip implementing the ideas of this paper was fabricated in a 0.25-μm digital CMOS process. The intended application of the filter is channel selection in an 802.11a/Hiperlan2 Wireless Ethernet receiver. The chip dissipates 9 mA, occupies an area of 0.7 mm2 , and maintains a signal/(noise+ IM3 distortion) ratio of at least 33 dB over a 48-dB signal range, with good blocker immunity. This performance represents at least an order of magnitude improvement over existing channel selection filters, even those that do not achieve disturbance-free operation
