IC Design

Prototyping is a lengthy process since it involves a lot of sub-processes; from design conception, circuit layout up to the PCB integration. An efficient IC prototyping process enables designers to quickly generate multiple trial layouts. Prototype and Prototype Manufacturing Service are an ongoing effort for PrototypeXpress. Getting from a concept idea to a working prototype is often the first stage in developing a successful product.

Our major IC design projects are:

  • Design of receiver chipset for PHS phone
  • Design of chipset for IF section of DECT receiver
  • Design of chipset for Digital AMPS Mobile receiver
  • Design of IF section of GSM transceiver chipset
  • Design chipset for DECT handsets and modules
  • Design of 1V CMOS Pager chipset
  • Design of GPS RF IC
  • Design of GPS Baseband IC
  • Wireless LAN IC redesign
  • Wireless LAN 802.11a IC design
  • Design of 10 Gbps ICs, including Post amplifier, Transimpedance Amplifier and Laser diode driver
  • Redesign of GPS RF IC
  • Redesign of GPS Baseband IC
  • RFID tag IC and module

 Design of IF Section of GSM Transceiver Chipset

6 patents issued and chipset has been used in mass production of Fizz and Spare mobile handsets.
 Design Chipset for DECT Handsets and Modules

Two patents issued. The chipset has been used in Siemens DECT handsets and Alps DECT Module. 
Design of 1V CMOS Pager Chipset
This chipset has been designed with 0.35 CMOS technology. The results have been two technical papers presented at IEEE IC design conferences. 
 Design of GPS RF IC

This chipset has been designed with TSMC 0.35um CMOS technology. This chip is interfaced with the Baseband unit that provides further processing on the signal. 
 Design of GPS Baseband IC
Four patents issued. The baseband performance has been tested and approved by implementation on Altera FPGA circuits.
 Wireless LAN IC Redesign

This IC has been mass-produced and used in 802.11b wireless LAN devices.
 Wireless LAN 802.11a IC Design

Four patents filed and the IC has been used in 802.11a WLAN equipment.
Design of 10 Gbps ICs, Including Post Amplifier, Transimpedance Amplifier and Laser Diode Driver

Design of ICs in 0.13 um technology, several key patents filed. 
Redesign of GPS RF IC

This chip has low power consumption in comparison to the last sample and in accordance to its structure occupies a smaller place than the other one. This chip has the ability to change the signal path gain (VGA). This chipset has been designed with 0.35um CMOS technology.

This RF chip and a full Arm-based FPGA for Baseband have been developed. First full signal locked off the air was received in the first week of May 2004.
 Redesign of GPS Baseband IC

The target is to design and implement a GPS Baseband Processor on a FPGA. This FPGA has the ability to lock and extract the transmitted data from 12 satellites simultaneously.

Low power consumption of this GPS makes it suitable for use in mobiles and hand watches. The design has standard AMBA buses so it can easily be used beside an ARM processor.
 RFID Tag IC And Module


The target of this project is to design and manufacture an RFID chip with average range of 10 meters and data rate of 50Kbps in the frequency of 2.4 GHz. This chipset has been designed with 0.18um CMOS technology.

This chip has the ability to receive energy from radiated RF signal, reading from and writing to EEPROM Anti Collision algorithm and is accessible to 70 units of seconds.

This chip works in two frequency modes: 2.4 MHz and 100 MHz and it can work in active and/or passive states.
