New IPs From ChipIdea Achieve Mass Production Status

Tagus Park-Porto Salvo-Portugal-November 26, 2003, ChipIdea Microelectronics SA announces that two new IP cores from its vast IP portfolio for embedded SoC applications have successfully achieved Mass Production status 1. CI3157va--10-Bit, 100kHz, 3.3V SAR ADC This IP core was designed for 0.18um CMOS single-poly and can be retargetable into any sub-micron CMOS technology with 2.5V/3V supply.

All biasing circuits are included, with only the need of an external reference voltage to define the full-scale range. This voltage could be derived from the analog supply voltage. A power down capability is included with less than 1uA of standby current. An analog multiplexer is provided to enable selection from 4 inputs. This IP core is suitable for application as a microprocessor peripheric A/D converter. 2. CI8158va - 10-Bit, 1 MHz, 3.3V Current-Steering DAC The CI8158va is a 10-bit auxiliary DAC core cell designed in 0.18um CMOS single-poly and can be retargetable into any sub-micron CMOS technology with 2.5V/3V supply.

This IP core uses a current-steering D/A converter followed by an output voltage-mode buffer. Due to its architecture, the conversion characteristics exhibit excellent linearity. This IP core is ideally suited in low-power applications requiring low resolution and medium speed.
