STKM2000 SERIES

STKM2000 ARCHIT ECTURE Tech no logy

The STKM2000 Series developed by SGS-THOMSON Microelectronics uses an advanced BICMOS silicon gate process with dual polysilicon layers and dual metal layers. This process is optimized to achieve high performance in digital CMOS applications. Depending on the operating supply voltage (10V, or 5V), the CMOS process behaves as an N-WELL technology (respectively with 2 µ gate length or 1.8 µ gate length) with operating speeds up to 30MHz. Thanks to the two metal layers, the digital part of the circuit can reach high gate density with low parasitic capacitances .

For analog functions, the STKM2000 series takes advantage of the bipolar structure:

Peripheral cells surround the internal active chip area to interface with its external environment.

Despite the row based architecture, “hard blocks” can be implemented with efficient floor planning organization.

STKM2000 Cell lib rari es

SGS-THOMSON Microelectronics introduces the “programmable” library; instead of working with a finite number of cells of the library , the designer has now access to an infinite number of functions.

Defining only some properties, the designer is able to create himself the cells needed for his application. For example, the following electrical parameters are accessible and adjustable:

● very high speed NPN transistor : f

● very high speed vertical PNP : f

= 6 GHz

= 2.5 GHz

This allows high gain - bandwith operational amplifier (50 MHz), low noise input amplif ier, short propagation delay comparator, ... With the same BICMOS process, the analog CMOS performance come from the high density CMOS structure with a double poly layer for accurate capacitors, low consumption CMOS amplifier (30 µA), CMOS switches, high accuracy switched capacitor filter s (up t o 100 kH z f or cent er frequency).

STKM2000 cell concepts

SGS-THOMSON Microelectronics has predesigned and precharacterized c ells which are selected, placed and interconnect ed on the chip to implement digital and analog cells having different height and supply voltages. In addition some macrocells are designed as fixed bloc ks , s o called “hard blocks” : filters, A/D and D/A conv erters; some hard blocks are automatically generated and parametrized from a compiler: S.C. filters, PLA, RAM, ROM. ..

● gain-bandwith product

● phase margins, frequency compensation

● output buffer cur rent

● biasing currents

● resistor, capacitor fields

● current, source or sink

● adjustable Ron switch resistor

● supply voltage assignment

The analog library is operating in a large voltage range: 3V to 10V.

The basic analog library contains:

● 60 analog CMOS functions

● 25 analog BIPOLAR functions

From single transitor to 12 bits A to D converter (with autocalibration), each setup becomes possible.

The digital CMOS library uses the same flexibility with a complete set of basic digital functions (NAND, NOR, Flip-Flop, ...) and some cell generators:

STKM2000 chip topology

The chip is optimized versus the cell com plexity , in a row based structure with different heights.

● register, counter, logic comparator, ...

More than 60 digital cells are available.
