ADC

We offer ADC development services that combine expertise in analog design and logic/digital circuit design.
The demand for ADCs used alongside various sensors is increasing due to the electrification of automobiles, digitalization of industrial equipment, and network compatibility of sensors enabled by IoT. SANEI HYTECHS aims to offer design services that reliably provide ADCs with the performance required by our customers, drawing upon our proven track record in developing multiple ADC methodologies and our consistent capabilities in circuit design, layout, and evaluation.

Development of ADCs compatible with various sensors

We are particularly focused on the development of ADCs (Analog to Digital Converters) within the realm of analog LSIs. ADCs are widely used in locations where sensors are employed. After receiving physical signals through sensors, some form of ADC is required before processing them as digital signals.
The demand for ADCs used alongside various sensors is increasing due to the electrification of automobiles, digitalization of industrial equipment, and network compatibility of sensors enabled by IoT. We provide design services for ADCs that are either integrated into sensor LSIs or used in conjunction with them.
ADC Application Examples
When incorporating an ADC into a sensor LSI, it is not sufficient to rely solely on analog circuit design. To achieve satisfactory performance, it is necessary to consider the sensor's characteristics when selecting an ADC, design layouts with parasitic effects in mind, and prepare an environment for accurate performance evaluation. Our company has a track record of developing multiple ADC methodologies, allowing us to support the selection of ADCs based on sensor characteristics. Furthermore, by handling circuit design, layout, and evaluation in-house, we can resolve issues related to layout design considering parasitic effects and ensure an accurate performance evaluation environment. We aim to provide design services that reliably deliver ADCs with the performance our customers require.

Achievements in ADC Development

We would like to introduce our track record in ADC development. Although there are various circuit types of ADCs depending on the application, we mainly have extensive experience in the following three categories. In particular, for around 12-bit accuracy, we have a broad range of development experience across various frequencies.
 
Circuit Type Main Applications
Delta-sigma (ΔΣ) Measurement instruments, audio, high-precision sensors
Successive Approximation Register (SAR) General-purpose, microcontroller-integrated, low-power sensors
Pipeline Industrial & medical equipment, video, communication

ADC Performance Range and our development achievements and Plans

Environment for Designing ADCs

We possess EDA (Electronic Design Automation) tool licenses for in-house circuit design and layout. Being able to handle circuit design, simulation, and layout within our internal environment enables us to carry out development more swiftly and securely.
Additionally, we have development experience across a wide range of processes, including various foundries and customers' in-house facilities. We can also flexibly adapt to the installation of PDKs and the establishment of development environments.

Continuous Technological Development

To accommodate an even wider range of applications, we are working on in-house development of ADCs with higher resolution, faster speeds, and lower power consumption. In particular, as improved power efficiency and reduced power consumption are desired by all users, we will continue to make ongoing improvements in line with industry trends.
