G6, G62, G63 High-Speed, Low-Glitch /CMOS Analog Switches ESCRIPTION The G6, G62, G63 feature high-speed lowcapacitance lateral MOS switches. Charge injection has been minimized to optimize performance in fast sample-andhold applications. Each switch conducts equally well in both directions when on and blocks up to 6 V p-p when off. Capacitances have been minimized to ensure fast switching and low-glitch energy. To achieve such fast and clean switching performance, the G6, G62, G63 are built on the proprietary /CMOS process. This process combines n-channel MOS switching FETs with low-power CMOS control logic and drivers. An epitaxial layer prevents latchup. The G6 and G62 differ only in that they respond to opposite logic levels. The versatile G63 has two normally open and two normally closed switches. It can be given various configurations, including four SPST, two SPT, one PT. For additional information see Applications Note AN27.

Charge Injection Figure 4. Crosstalk APPLICATIONS High-Speed Sample-and-Hold In a fast sample-and-hold application, the analog switch characteristics are critical. A fast switch reduces aperture uncertainty. A low charge injection eliminates offset (step) errors. A low leakage reduces droop errors. The CLC, a fast input buffer, helps to shorten acquisition and settling times. A low leakage, low dielectric absorption hold capacitor must be used. Polycarbonate, polystyrene and polypropylene are good choices. The JFET output buffer reduces droop due to its low input bias current. (see figure.) Pixel-Rate Switch Windows, picture-in-picture, title overlays are economically generated using a high-speed analog switch such as the G63. For this application the two video sources must be sync locked. The glitch-less analog switch eliminates halos. (see figure 6.) GaAs FET rivers Figure 7 illustrates a high-speed GaAs FET driver. To turn the GaAs FET on V are applied to its gate via S, whereas to turn it off, - 8 V are applied via S 2. This high-speed, low-power driver is especially suited for applications that require a large number of RF switches, such as phased array radars.
