SYSTEM ARCHITECTURE

MGC3X30 are mixed-signal configurable controllers.

The entire system solution is composed of three main

building blocks (see Figure 3-1):

• MGC3X30 Controller

• GestIC® Library

• External Electrodes

3.1

MGC3X30 Controller

The MGC3X30 feature the following main building

blocks:

• Low Noise Analog Front End (AFE)

• Digital Signal Processing Unit (SPU)

• Communication Interfaces

The MGC3X30 provide a transmit signal to generate

the E-field, conditions the analog signals from the

receiving electrodes and processes these data digitally

on the SPU. Data exchange between the MGC3X30

and the host is conducted via the controller’s

communication interface or the Gesture Port. For

details, please refer to Section 4.0 “Functional

Description”

3.2

GestIC® Library

The embedded GestIC Library is optimized to ensure

continuous

and

real-time

free-space

and

tracking

(MGC3130)

concurrently. It is fully-configurable and allows required

parameterization for individual application and external

electrodes.

3.3

External Electrodes

Electrodes are connected to MGC3X30. An electrode

needs to be individually designed following the guide

lines from the ‘GestIC Design Guide’ for optimal E-field

distribution and detection of E-field variations inflicted

by a user.
