“For contributions to analog, mixed-signal, and digital integrated circuits, and outstanding leadership in microelectronics education and research and development.”

Wireless Sensors and IOT Modules

Many battery-operated IOT modules must be connected wirelessly to a "Gateway". GSC has developed a number of wireless sensor modules based on LoRa transceivers and also based on Bluetooth transceivers. The former can send data over longer distances, the latter have the advantage of a more popular standard and the capability of Over-The-Air-Updates. GSC can supply Wireless Sensors in low volume, or alternatively work with Clients under a Design Services Agreement. All communication links are encrypted. Wireless IOT Boards

Design Services

GSC offers design services help in a wide variety of areas including: analog and digital design (specializing in sub-micron technologies), system modelling, IOT sensor applications, and secure data-bases. These services can be either a time-and-materials contract, or a fixed-fee contract. In the latter, very well defined specifications are required before setting the fees. One approach is to define specifications based on time-and-materials, and then use these specifications for a fixed fee contract. Most of the integrated circuit design contracts require a Place-and-Route CAD program which must be supplied by the Client.

Ransom-Ware-Proof Database
with RfId Inventory Tracking

Data-base tables and GUIs are automatically generated from simple Excel files; data is stored in SQL database with no knowledge of SQL required. This enables simple and fast customization by GSC or Client or both. Critical data is encrypted at Client's choice. Logins require physical presence (RfID license file), no hacker from a distant country can access data-base. Licenses automatically changed daily. Full SSL/TLS data-encryption channels. Data-bases have four different independent back-up mechanisms (with rotation) and are also exactly rep[icated in cloud. Inventory tracking is available using RfId stickers (RfId readers are supplied).

Sensor Interfaces

GSC has a number of add-on boards for small-board-computers (SBCs) including the "Beagle-Bone-Black" and the "Raspberry Pi". These boards allow connecting 24-bit A/D converters (1" diameter), temperature/humidity sensors, strain gauges, accelerometers (for measuring bearing wear), and other boards using I2C and SPI digital interfaces. The boards include a real-time-clock, an EEPROM, and can be customized.

Digital DPLL's

All DPLL's have fractional-N division, and both serial and/or parallel bus programming. No off-chip components are required. Full-speed off-chip 50-ohm output drivers are available. Since loop-filter is digital, loop dynamics are process insensitive and scale with reference frequency. In addition, system simpulations are very accurate; you know exactly how the PLL will operate.

High Speed in 40G: 0.5-7.5 GHz DPLL in TSMC's 40G
Improved Jitter in 40LP: Second generation, optimized DPLL in TSMC's 40LP
Ultra Low Power in 28HPM: 2-9 mW, area < 0.06mm^2 DPLL in TSMC's 28HPM
DPLL Dual Loop Jitter-Cleaning: optimized for extremely low frequency references having excessive jitter
