Analog and Mixed-Signal Design
VivEng, Inc. is an analog mixed-signal and system-on-chip (SoC) design service company designing and offering state-of-the-art analog and mixed-signal integrated circuits and IP blocks to customers worldwide. Founded in 2009 and located in San Jose, CA, VivEng specializes in development of ultra-low-power design and power control, high-voltage analog design, power management (PMUs, battery chargers, switches and regulators), data acquisition and conversion, ultrasound sensors, and specialized IO libraries.
Semiconductor IP block design and development
VivEng offers analog circuits to be used as IP blocks, with an emphasis on low-power compact designs. We also offer testing and characterization support for IP blocks in your complete system. Examples: analog IP for TSMC 90 nm process; custom IO and ESD library.
SoC and ASIC Design
We develop custom analog and mixed-signal ICs with on-chip signal conditioning circuits, A/D and D/A converters, digital signal processing, power drivers, clock recovery and conditioning, clock distribution, adaptive supply control, and more. Example: VE1210, VE1212, VE1214 family of sonar ICs.
Concept development and evaluation
We offer concept development, evaluation, and analysis covering a wide range of physical systems (mechanical, fluidic, electromagnetic, electrochemical, etc.) especially as they apply to sensor systems for industrial, medical, and automotive markets. Examples: Analysis of magnetometer-based distance measurement; EDAMAME 3D modeling tool
System-level and PCB Design
We offer system-level design from the PC-board level to complex multi-board systems, including microcontroller- and FPGA-based systems. Examples: Evaluation board for VE121x IC family; Solar plant monitoring module.
Analog IP for modern SoC designs
We anticipate a continued proliferation of system-on-chip designs involving sensors and actuators and other analog interfaces, in some cases combined with one or more processor cores, memory, and wired or wireless interfaces. To address the need for analog blocks in such systems, we have developed a portfolio of analog blocks for advanced process nodes.
Today we offer silicon-proven analog IP in the TSMC 90 nm process and we are working to expand our portfolio to 65 nm and 28 nm processes. Our portfolio covers power management, clock generation, temperature sensing, light sensing, and thermal random bit generation. Our power management approach supports on-chip voltage regulation without external capacitors, plus power-saving schemes with multiple supply islands, making it well suited to mobile battery-powered applications.
We also offer custom designs involving adjustable or programmable sensing and signal conditioning, high-power drivers for actuator sub-systems, analog-to-digital and digital-to-analog signal conversion, and custom power management.
