ANALOG DESIGN
Experience in analog design :
- ultra low power/low voltage circuits
- voltage references
- voltage regulators
- supervisory ICs
- watchdog
- oscillators
- custom low power CMOS image sensors
- filters with switched capacitors
- high voltage switching parts
- A/D and D/A converters
- current-mode circuits
Design and realization flow
Analog design flow is dependent on the analog system structure,
supply voltage, operating voltage, output currents, etc. Basically
two different kinds of integration are used in ASICentrum :
 |
 |
| analog ASIC internal
structure |
technology |
advantages |
disadvantages |
|
full custom design
|
CMOS, BiCMOS |
universal usage |
- higher NRE
- longer design time
|
|
MMA gate arrays
|
CMOS |
low NRE
|
limited
selection of parts values (resistors, capacitors) |

Design process, evaluation and following production of analog circuits
step by step in ASICentrum :
1. DESIGN SPECIFICATION
- customer's development assignment
- creation of the circuit specification
2. CIRCUIT DESIGN
- technology selection
- testability analysis
- schematic creation (Design Architect)
- verification (Eldo)
- layout design (IC Station)
- post-layout verification (Eldo)
- test program development
3. PROTOTYPING
- type of samples is technology dependent
- samples production
- samples measuring
4. PRODUCTION
