[Ideas For Design]
Quad op amp performs matching of discrete npn transistors
Many discrete analog circuits require precisely matched transistor pairs. Logarithmic and antilogarithmic functions, differential amplifiers, and multipliers possess inherent matching features generally not obtainable with discrete components. The... — Contributing Author

Low-voltage oscillator features increased spectral purity
A common problem in crystal sinusoidal oscillators is the excitation of unwanted modes of the quartz crystal that degrade the spectral purity of the oscillator. This problem is significant in overtone crystals, particularly if the oscillator is... — Contributing Author

[Ideas For Design]
Design a 3-pole, single amplifier, LP active filter with gain
Designs for single-amplifier, twopole, low-pass, active filters with gain are relatively common in the literature, but little information is available for such filters with three poles. Determining the component values for a three-pole filter requires... — Contributing Author

[Ideas For Design]
Piezoelectric alarm rings clear as a bell
A common piezoelectric alarm, such as the Murata (Smyrna, GA) PKB5-3A shown, has many valuable attributes. It is compact, lightweight, efficient and reliable. However, the loud, high-pitched sound output can be quite irritating in many applications.... — Contributing Author
