Rather than claiming a large portfolio of products, Dolphin has chosen to offer the best solutions for various optimization criteria:
low power, high dynamic range, low distorsion, low silicon area. Such solutions, based on delta-sigma or PWM techniques, can be easily embedded in customer application schematics, be they based on Class D for high Output-power or usual Class AB with a reduced Bill of Material.
Overview of Analog Front-Ends
For your complete and competitive System-on-Chip, you
need our analog products which eliminate any requirement for competency
in analog design: consult their promotion sheets, datasheets, and their
associated simulation models and test benches to simplify your evaluation
and design in.

By selecting our Analog Virtual Components, designers
have the insurance of a perfect match with their targeted application.
Each Virtual Component is delivered at hard level, with
all required materials such as:
- Specifications & User’s manual (incl. SoC integration
guidelines)
- Functional & Timing Digital Model (F&TDM)
- Industrial test specification
- Timing file for STA
- Footprint (LEF)
- Physical netlist for LVS purpose
- Layout (GDSII) (to targeted foundry)
Product line description - Our Experience in Analog Front-Ends
Active in the market of ViC since 1987, the company strategy
has been to push performances, at the expense of aggressive patenting
and proprietary development based on its know-how in mixed signal design.
Using our ViC, SoC designers have the insurance of relying on the most
optimized methodologies not only in terms of performance (ratable through
the figure of merit) but also in terms of Reliability and Yield.
JAZZ Virtual Components have been retargeted in a wide
range of CMOS silicon processes or bulk or SOI and are delivered fully
optimized as a "black box" so that Mixed Signal SoC Integrators
do not need analog competencies to integrate them into their SoC.
Core products and peripherals
Standard products for ADC and DAC are developed
upon a range of well proven core architectures each optimal in terms
of its frequency spectrum, its SNR template and its silicon expense.
A choice of peripherals aims at ensuring customization for the best
match with each user’s needs. Our offering is completed with
a wide range of services: process retargeting, ViC training, SoC
integration, on-site design consultancy… These enable “the
three F’s” of personalisation for user's need: functions,
features and form factor, while the most appropriate architecture
is configured and migrated according to the targeted technological
process in appropriate Time-to-Fab.
