ASIC for analyzing and processing fingerprint signature

Fingerprint sensor analysis ASIC

This ASIC enable to analyze the performance of a fingerprint sensor.

The ASIC can read out a fingerprint sensor, analyze the fingerprint and calculate a fingerprint signature.

The design was a backend job for Presto, where the customer delivered the RTL code for synthesis and layout.

Presto assembled the chip with both externally and internally developed IPs.
For fast IO communication, an LVDS IP was developed by Presto.

Top technical features:

• CMOS 0.18 um process
• 100 MHz internal clock frequency
• PLL
• LVDS
• Highly linearly RF-DAC based transmitter with output power control in the range -10dBm to 1 dBm
