Customer Trend #1 : Mobile Device Performance

Audio Quality Experience

Smart phones require

– High acoustical output

– Small form factor

– However, conflicting demands for loudspeaker

Problem

– Loudspeaker damaged when used beyond its safe physical limits

Need Push loudspeaker to its limits amd PROTECT against damage:

– Push to achieve maximal acoustical output

– Protect mechanically: diaphragm displacement (excursion) from reaching its

max limit

– Protect thermally: temperature of voice coil from reaching its max limit

Solution : Sensor

– Prediction of excursion

– Estimation of LS temp

L/HDR

(106-848kbps)

COMPANY INTERNAL

Drive NFC VHBR to 27Mbps

Two main practical applications:

eGov (e-passports for security) – Trend to increase amount of stored (biometric) data

– Currently very long read and write times (up to 10 s)

– Much Shorter read times allow ePassport gates

19

NFC – Transfer large blocks of data (e.g. synchronization of phone & PC)

– Peer 2 peer file exchange on-the-go

COMPANY INTERNAL 20

Objectives : Drive NFC to VHBR Increase the data rate of 13.56 MHz inductively coupled systems

greater 848kbps to 27Mbps

Introduce new modulation scheme capable of transferring both – Power

– Very High data rates

Analog front end – Power harvesting

– Demodulation

Digital signal processor – Equalization and Bit recovery

Low cost , low power consumption (For smart Card)

Drive VHBR for ISO standard to acceptance

COMPANY INTERNAL 21

Inductive coupling

Card usually passive (powered by magnetic field)

Reader Card: direct modulation of magnetic field

– TYPE A at 100% , TYPE B at 10% Amplitude

Modulation (ASK)

Card Reader: load modulation (10% , BPSK, NRZ-L)

L/HDR : 106K, 212, 424, 848Kbps

VHDR : 1.6M,3.2M,6.7M

Fc : 13.56 MHz

COMPANY INTERNAL 22

Investigated various modulation

Multiple amplitude and PSK Modulation

No carrier – Large reduction of

energy compared to

AM

– Hard to lock a PLL to
