My responsibilities as the Manager of RF embedded systems included:Building and running the the team that was responsible for the understanding the product's compute and control systems for very complex cellular rf transceivers and the implementation of the subsystems of the part which included system design, digital design and verification, and development of the firmware that controls the system.My team was responsible for two transceivers during this time. The first was a low cost part to be targeted a price point applications and expected for high volumes. I drove the team from definition to tapeout in the embedded portions of the product inlcuding the pre silicon verification. The part taped out an was brought to the lab for first bring up. The part was operational within minutes was able to demonstrate recieve and transmit operation within that time.My team worked on projects accross different time zone and scope, including audio designs for the cellular market which once again had first pass functional success.As the leader of the the team, it was also my responsibility manage the team for performance and build the team further to attain higher design capacity for numerous product requests that were coming in. As a team we built the team from 10 engineers to 28 engineers in the span of 3 years. All the hires became strong contributers to the programs they were or are working on.

I led a team of wireless mixed signal design, verification, firmware developers and systems engineers. We were responsible for the design and development of transceiver integrated circuits for the global cellular marketplace. During this time the team developed the first sawless 2g/3g transceivers in the world and first LTE part in Japan. My team did the digital design and top level verification. I personally led the development of the verification plan for top level simulations including the firmware to control the system.

Manager of a multi site group responsible for the system design and digital content for multimode cellular transceivers and power management devices,including their verification. Numerous new methodologies were developed in the design and verification of these complex mixed signal devices. John and his team integrated what is believed to be the first complex cellular transceiver that had an embedded processor on the same die as the RF. This architecture allowed OEM cell phone manufacturers reduce part count and simplify the communication to an API that was easy to configure for multiple products.

I managed a team of 30 engineers and directed the activities of team members in multiple sites in the development of a multimode baseband IC. The total number of staff was over 100 and coordinated the overall team from specs to tapeout. The project set new standards for functionality for a first pass baseband IC. While being the chip lead I also was the verification architect defining what the plan was and how it would be done. Phone calls on the cellular system were made on the date of the first part arrival. Phones were shipped on GSM/AMPS/IS136/Nextel and Government security systems.

Led the development of of an AMPS low cost chipset including a baseband SOC with custom DSP. Employed SPW, Verilog, and Synopsys for the toolset. I defined all the interfaces for the power management, firmware interface, and the SOC. The part taped out and RX and TX were operational in the first days.

Libertyville Illinois

Lead the development of custom integrated circuits for analog cellular phones. Projects included design of analog and digital circuits that were either stand alone or integrated into early SOC products. I personally designed analog circuits for power management parts and did top level work for the tapeout including layout of circuits. I completed lab evaluation of the parts and built a stand alone board for additional checking.

I was a member of the Motorola Automotive and Industrial Electronics Group. Within the group I was a team member of the Electronic Appliance control group and the Automotive Engine Control team.As a member of the appliance team I was assigned to develop controllers for dishwashers and other appliances. I was responsible for the electrical design, testing, layout, and bring up in the Motorola and customer factories.I transferred to the automotive team and worked on on control modules for a multinational car manufacturing company. I developed the hardware and worked with other team members on the firmware implementation and testing in the lab. I was also tasked to develop a portable means of reprogramming the engine controller for the customer for their track testing. Finally, I wrote the test code for testing the control in the factory using HP test equipment.

Milwaukee Wisconsin

I was part of the Johnson controls cooperative engineering program. I was assigned a variety of tasks relating to building automation during this time.Key accomplishments were:Changing code to accommodate foreign language use by customers.Lab work including reflashing systems.Bringing up a system to move data from one CAD environment to another.
