3.0 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.
