What ALD's "FUNCTION-SPECIFIC" Approach? I.C. design techniques software learn. Optional simulation models, macromodels subcircuits available. Design breadboard with completely specified, shelf, standard I.C.'s normally Minimizes risk proves your design works before committing custom chip. you're sure your volume justifies custom chip just yet, into production with standard linear I.C.'s transition custom I.C. when suits -AND- without major redesign. Optimizes your surface mount program SOIC package combine your linear I.C.'s onto chip. FAST: 12-16 weeks normal lead time once your "Function-Specific" order placed -AND- don't have spend weeks months becoming I.C. designer order develop your circuit. power, voltage, precision Silicon Gate CMOS using ALD's precision ACMOS process provides linear I.C.'s that match-up with digital circuits you're using today's voltage, power systems.

Packaging, Rel, Non-Standard Cells Your packaging requirements with industry standard PDIP, CDIP, SOIC, PLCC, DICE. Standard counts Special packages available. High reliability military processing available, ALD's industrial enhanced reliability "A+" program. products (=standard cells) continually being announced ALD. Should your design require cells currently announced, check with what have coming fits with your plans. event ALD's "Function-Specific" approach doesn't meet your needs, will work with your "full-custom I.C."

Frequently Asked Questions Regarding "Function-Specific" Circuits this like linear array? array chip filled with fixed transistors, diodes passives which must design with interconnect following I.C. design rules sometimes using specialized software hardware. "Function-Specific" standard cell approach with defined I.C.'s (standard parts) configure using your standard design practices, resulting completely custom chip. "Function-Specific" have completely characterized higher level building blocks (such various operational amplifiers) that were carefully developed integrated. What about critical nodes? Will circuit work chip form? already solved this problem. critical nodes within devices themselves inside amps, timers, comparators, etc. normal input, output, power supply nodes noncritical designed withstand parasitic stray capacitances. result, integrating variety devices single chip presents particular problem long breadboard works. "SPICE" available simulation? supports simulation models, subcircuits macromodels. PSPICE with this simulation conducted either customer personnel, supplement breadboard. does take 12-16 weeks? Because each I.C. different must have unique, complete custom mask generated, wafers fabricated tested, units packaged, final tested, shipped. resistors capacitors integrated "Function-Specific" I.C.? Yes, resistors capacitors integrated your custom linear I.C. precision resistors different types capacitors? bring leads where want them place your precision passives chip. digital circuits "Function-Specific" chip? Yes, contact list digital level gates that currently available "Function Specific" digital library. diodes available chip? MOSFETS diode-connected configuration. have isolated circuits chip? There typically 120dB isolation between circuits. much does cost? Since full custom program, depends complexity circuitry involved. There cost components. first time, nonrecurring engineering cost setting implementing project. second component unit cost, which depends complexity, packaging, testing, volume ASIC chip. I.C. chip usually costs much less than buying individual parts assembling them onto circuit board.
