Abstract
Logarithmic converters have an important place in signal processing and the bipolar transistor can be an invaluable element for generating such functions. As with most any design, there are tradeoffs. With logarithmic converters composed of bipolar transistors, response time must be weighted against dynamic range. Several basic circuits for log and antilog generators, with differently weighted operating characteristics, are analyzed and, applications are described.
