Features of pipeline ADC IP and cyclic ADC IP

The pipeline ADC IP and cyclic ADC IP developed by our company combine high performance and efficiency to support a wide range of applications.
The main features are as follows.

High power efficiency

We have adopted a design that minimizes the power consumption of the entire circuit, including the VREF buffer. Our unique circuit technology has achieved high power efficiency.

VREF buffer built-in

There is no need to prepare a separate VREF circuit that requires driving capacity externally, which contributes to simplifying the system and improving design efficiency.

Digital correction function

High-precision correction is possible by running a correction program before shipment or at startup without using a multiplier circuit for gain correction.

Multi-channel support

We have adopted a design that allows multiple channels to be easily installed, supporting a wide range of applications.

Low delay pipeline

We minimize the delay time until the conversion process is completed, enabling high-speed and efficient data conversion.

Evaluation Results were generally in line with the target specifications. We will analyze the differences between the design values and the evaluation results and incorporate the findings into the next design iteration.

Provision of in-house developed ADC IP and process porting

Our pipeline ADC and cyclic ADC IP can be provided for various applications. We also provide custom design services based on the process and specifications according to your needs. If you are looking for an ADC IP solution, please feel free to contact us.

Provision and support of evaluation environment

At our company, we not only design semiconductor circuits, but also integrate IC prototyping, development of evaluation environments, and evaluation. The following issues are particularly important for analog circuits.
 
  • The effects of semiconductor element mismatch
  • Changes in power supply and temperature
  • The effects of power supply and circuit board noise
  • The effects of parasitic resistance and parasitic capacitance

Due to factors such as those mentioned above, it is said to be difficult to achieve device performance as designed. We pursue advanced evaluation technology to eliminate these external factors as much as possible and accurately measure high-precision circuit characteristics. For more information on evaluation boards and systems, please see the link below.
