SYSTEM ARCHITECTURE

The MGC3130 is the first product based on Microchip’s

GestIC technology. It is developed as a mixed-signal

configurable controller. The entire system solution is

composed by three main building blocks (see

Figure 3-1):

• MGC3130 Controller

• GestIC Library

• External Electrodes

3.1

MGC3130 Controller

The MGC3130 features the following main building

blocks:

• Low Noise Analog Front End (AFE)

• Digital Signal Processing Unit (SPU)

• Flexible Communication Interfaces

It provides 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 MGC3130 and the

host is conducted via the controller’s communication

interface. 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 Position Tracking

and Gesture Recognition concurrently. It is fully-

configurable and allows required parameterization for

individual application and external electrodes.

3.3

External Electrodes

Electrodes are connected to MGC3130. An electrode

needs to be individually designed for optimal E-field

distribution and detection of E-field variations inflicted

by a user.
