Abstract: A hybrid edge termination structure and method of forming the same. The hybrid edge termination structure in accordance with the invention is based on a junction termination extension (JTE) architecture, but includes an additional Layer of guard ring (GR) structures to further implement the implantation of dopants into the structure. The hybrid edge termination structure of the invention has a three-Layer structure, with a top Layer and a bottom Layer each having a constant dopant concentration in the lateral direction, and a middle Layer consisting of a plurality of spatially defined alternating regions that exhibit the electrical properties of either the top or bottom layer. By including the second layer, a discretized varying charge profile can be obtained that approximates the varying charge profile obtained using tapered edge termination but with easier manufacturing and lower cost.

Abstract: A high speed probe attenuator has an attenuator with a plurality of resistors connected in series between a probe input and an instrument output. A plurality of capacitors are coupled in parallel with pairs of the resistors in an interleaved fashion to spread the frequency correction along the attenuator. The output of the attenuator is coupled by a large diameter coaxial cable to a test instrument. The result is a high speed probe with no dribble-up effect and no overshoot.

Abstract: A d.c. restore circuit for a multi-channel remote video interconnect circuit is situated at the output end of the interconnect circuit for minimum capacitive loading and to reduce power requirements for a video driver at the input end of the interconnect circuit. A resistor/diode voltage divider network is coupled between the output of the interconnect circuit and the cathode or grid of a CRT, with a capacitor in series with the output of the interconnect circuit to block any d.c. component of the video signal from the video driver. A fixed voltage is applied at one end of the divider network and a variable current source is coupled to the other end. The current from the current source determines the d.c. potential at the cathode or grid.
