multiplier, fabricated on an advanced dielectrically isolated
complementary bipolar process. It generates the linear product
of its X and Y voltage inputs with a −3 dB output bandwidth of
250 MHz (a small signal rise time of 1 ns). Full-scale (−1 V to
+1 V) rise to fall times are 2.5 ns (with a standard RL of 150 Ω),
and the settling time to 0.1% under the same conditions is …
