ASIC PRODUCTS DESCRIPTION
With the STKM2000 series, SGS-THOMSON
Microelectronics introduces the “state of the art”
product for analog signal processing, chain from
sensor to actuator.
The introduction of new concepts (cells librar y and
CAD) opens the design of analog functions and
mixed analog and digital circuits with a safe and
powerful approach. This new A SIC approach is t he
combination of innovative :
● BICMOS process
● Mixed libraries (ANA LOG + DIG ITAL)
● Generators and compilers
● “User friendly” CAD system
● Customer int erf ace

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
T
= 2.5 GHz
T
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.
