Quickfilter Technologies Raises $4.8 Million in Funding

Quickfilter Technologies, Inc., a fabless semiconductor company that develops mixed-signal ICs based on a programmable finite impulse response (FIR) engine for digital signal processing, announced that it has closed its third round of investor funding totaling $4.8 million. The Series C financing, raised by private investors including several private equity firms, will enable the company to expand its marketing strategy to increase high-volume design wins as well as develop new products for its target markets including consumer audio, automotive, industrial controls and medical electronic systems.

“The Quickfilter management team is pleased to have this strong level of support from our investors and views the Series C funding as a solid endorsement of our team, our technology and our product roadmap,” said Bob Silco, Quickfilter Technologies founder and Co-CEO.

Quickfilter Technologies currently offers two products:

  • The four-channel QF4A512 Programmable Signal Converter is a highly integrated sensor interface comprising an analog front end, an analog-to-digital converter (ADC) and precision digital filtering. The QF4A512 chip can handle from 1 to 4 analog input channels and outputs converted data via a high-speed serial port.
  • The single-channel QF1D512 Simple and versatile FIR engine (SavFIRe) is a programmable, 512-tap FIR digital filter designed to add precision digital filtering to an application without the need for extensive redesign or additional computational horsepower. The QF1D512 chip’s extremely low power (~ 10uA @ 1 Ksps), small footprint (3x3mm QFN package) and low cost make it an ideal filtering solution that can be added between an existing ADC and the host controller. It can also be connected as a co-processor device for controllers with embedded ADCs. Previously adding precision filtering to an application would require moving to a larger core (MCU, DSP or FPGA), thereby increasing costs, power consumption and board space.

Quickfilter Technologies also offers Development Kits for the QF4A512 and the QF1D512 as well as application-specific evaluation boards and reference designs.

“The Series C financing will enable Quickfilter to concentrate on increasing high-volume design wins in our target markets,” said Don DiDonato, Vice President of Worldwide Sales for Quickfilter Technologies. “For example, we are seeing success and increasing customer acceptance in the consumer audio, automotive, industrial controls and medical electronics systems markets. To help keep this momentum going, we have recently announced a series of reference designs for specific applications within the consumer audio arena which are targeted to drive great growth in that segment. As we work with all of our customers on their future product roadmap needs, we will also use the Series C financing to define and develop new products.”

About Quickfilter Technologies
Quickfilter Technologies, Inc utilizes patent pending techniques for implementing programmable ICs that allow an engineer to design a custom circuit for signal processing without the cost and complexity of programming a DSP. Using the Quickfilter solution, it is possible to create, and begin operating, custom filtering solutions in less than five minutes. Quickfilter’s products are ideally suited for sensor-based applications in consumer audio, automotive, industrial monitoring and control, medical equipment, homeland security and engine control applications. The Quickfilter solution comprises over a dozen individual component functions, both analog and digital, into a single integrated circuit (IC) that is programmable using Quickfilter software. This enables customers to rapidly complete a design at significantly lower cost and higher performance. In addition, the IC can be reprogrammed in circuit during design, at the time of shipment or in the field. Quickfilter Technologies Inc. is a private equity funded fabless semiconductor company founded in 2003 by Bob Silco and located in Allen, Texas. The company is developing a family of programmable mixed-signal integrated circuits that convert noisy analog signals into clean, usable digital signals.
