Abstract :
A series of logarithmic amplifier designs based on follower type circuits is described herein. One circuit contains only three components and covers the range 10-10 to 10-3 amp. Another circuit contains four components and covers the range 10-7 to 1 amp for pulsed operation. A circuit which has been radiation hardened and temperature compensated for pulses in the range 10-5 to 1 amp is shown.
