I have always maintained that a valid restatement of Murphy's Law1 is that the laws of physics always work, whether you are expecting them to or not. Writing Analog Devices' "Rarely Asked Questions" column has brought me many interesting letters from my readers sending me examples of situations where this is abundantly true - and this vicarious experience has increased my ability to determine the unexpected causes of arcane problems.
Please contact me if you have problems with precision analog and sensor circuitry which you would like me to investigate, or if you require advice on how to tackle a project in high-performance analog electronics.
