Design and Performance of an Integrated Circuit Flip Flop with Photocurrent Compensation

The design and testing of a dielectrically isolated integrated circuit Set-Reset (RS) flip flop is described. The flip flops were fabricated with bipolar transistors having a primary photocurrent sensitivity of 3-5 × 10-11 mA/rad(Si)/s. The flip flops were capable of being switched on clock command during a 400 nsec electron beam pulse with a peak dose rate of 1.6 × 1011 rad(Si)/s.
