Upgrade for mixed signal process and libraries

PolarFab has improved its 6in complementary BiCMOS (c-BiCMOS) RFBC/ABC3 processes to provide reduced die sizes and decreased design times.

PolarFab has improved its 6in complementary BiCMOS (c-BiCMOS) RFBC/ABC3 processes to provide reduced die sizes and decreased design times.

Both processes are used for a variety of analogue and mixed-signal applications such as low-noise amplifiers, photodetector integrated circuits (PDIC), line drivers and power management.

Three digital cell libraries have been added to the RFBC/ABC3 standard cell library portfolio in order to reduce design times and increase first pass success for designers.

The first library, optimised for synthesis, place and route (SP and R), is a 72-cell library that includes logic (Verilog) and synthesis views.

Users can employ proven SP and R flows to reduce logic circuit design time.

The synthesis views are compatible with industry leading EDA tools such as Synopsys and Cadence.

A Library Exchange Format (LEF) file for automated place and route tools is also included.

The second library, provided for a schematic-based flow, is a 30-cell, standard cell library, giving designers a more area-efficient alternative to the SP and R library.

Lower gate count circuits can be created using proven silicon building blocks, saving time and increasing first pass yield.

The third library is a 10-cell pad cell library that incorporates analogue, input, output, and bidirectional pad cells and is ESD tolerant up to 2kV human body model (HBM).

The silicon-verified pad cell library works with industry standard design tools, reducing design times and increasing first pass success for designers.

In addition, PolarFab has added a high-sheet rho (HSR) resistor to its RFBC process, featuring up to 2000ohm/square to provide reduced die size as well as lower parasitics for high-value resistors.

The new HSR resistor also improves bandwidth for amplifier applications.

The RFBC process is a 0.8um c-BiCMOS process that supports chips running at speeds up to 1.5GHz and is suitable for consumer applications requiring high-performance amplifiers.

PolarFab's ABC3 process, also a 0.8um c-BiCMOS process, supports chips running at speeds up to 1GHz and is suitable for a wide range of analog and mixed-signal applications.

Both processes can safely handle 10V supplies and offer a CMOS low voltage rating of 5V.

Pricing and delivery is dependant on customer requirements.
