Analog & Mixed-Signal IC Design
Ciris Semi begin with silicon-proven analog and mixed-signal building blocks from which our ADCs, Power Management , PLL and other world-class complete Analog ICs are built
General purpose
- Power on Reset with Brown out voltage detector
- Instrumentation amplifier & PGA
- Temperature sensors (with 10bit,1Ksps, ADC)
- Ring Oscillator (128 KHz, 4MHz , 20 MHz) (No external component)
Data Converter(ADC / DAC)
- Application optimized ADC and DAC circuits from low power to high-speed to high-resolution ranging from 8-bit to 14-bit.
- Successive approximation AD converters
- Pipeline AD converters.
- 2nd Order SC SD Modulator.
- Single-slope with accelerated ramp AD converters.
- Current Steering DACs (Single /Dual /Triple)
Power Management
- DCDC Switching Buck Converter, range 50 – 800mA. Low quiescent current, high efficiency.
- Linear Voltage Regulators range 50 – 500mA
- LED Driver 100mA
- Experience in BCD process
PLL
- Integer PLLs (From MHz range up to 2.8 GHz)
- Spread Spectrum PLLs (Lower power spread over a wider band to reduces EMI)
DLL
- Master DLL / Slave DLL / Compensation block (150 MHz to 533 MHz)
