considered to be equivalent to the zener diode, except that it provides a constant cur-
rent rather than a constant voltage.
1.2 The first JFETs and op amps
Another major contributor to both JFET and CRD technology was Siliconix, which
was founded in 1962 by several former Texas Instruments’ engineers, and a former
Bell Labs researcher. During the first few years of its existence, Siliconix created and
developed JFETs, in which it became the undisputed market leader. Siliconix also
developed several product families of CRDs, as well as later pioneering the power
MOSFET.
