Abstract :
An eight channel logarithmic pulse rate measuring circuit has been designed for use with a tissue equivalent gas proportional counter system. The use of thermal feedback in monolithic silicon microcircuitry is described together with its application to the temperature stabilized logarithmic pulse counting circuits. With this form of temperature compensation, each channel exhibits a logarithmic characteristic which is absolutely accurate to within 5% over 3 decades for the temperature range from 0°C to 60°C.
