Optical Mouse
Sensor:
Developed system theory and core design for a
very low power optical mouse chip. This chip includes an image sensor
with pixel-plane analog processing, post-processing logic and
microcontroller interfaces.

Organic TFT
RFID Tag:
Managed team of designers in development of a
novel, extremely low-cost organic
TFT-based HF RFID tag. The project included process development support
such as design rule development, device modeling and detailed device
analysis. Circuit development led to a significant number of patent
applications.

Integrated
Baseband Filter for Multi-Standard Receiver:
Developed baseband filter cell to
support multiple communications standards from UHF up to 6 GHz
operation. This circuit optimizes SFDR and includes an automatic tuning
system. This is one
of many such circuits developed at RadChips. |

Mobile DVB TV
Tuner:
Developed advanced mobile TV tuner direct-conversion
front-end cells from RF input to baseband output. Advanced fractional
frequency synthesis techniques were used to achieve exceptional phase
noise
performance. Power reduction strategies such as tunable RF circuits,
SFDR and SNR optimization with signal level and filter phase
equalization were used.

Zero-C Active Probe:
Developed a zero input capacitance, low-leakage high-voltage active
probe for organic TFT measurements. The device operates as an
electrometer front-end for oscilloscope measurements and minimizes
disruption to circuits utilizing low-mobility transistors.
