Design and Implementation of Ultra Low Power Edge Coded Signaling (ECS) Transmitter Architecture for IoT Devices

Abstract

To improve data rates and reduce power losses in Internet of Things (IoT) devices, a dynamic edge-coded signaling approach is utilized to evaluate the 16-bit segment transmitter design. The Edge coded signaling (ECS) transmitter architecture comprises three fundamental components: an Encoder, a Toggle counter, and a finite state machine. To enhance data rates, an edge coding approach is applied by the transmitter's function on both the rising and falling edges of the broadcast pulses. This research presents an efficient transmitter architecture optimization that transmits pulses solely on the rising and falling edges of the segment bits in each encoded segment. The transmitter includes an encoder that counts the number of ones in the data and pulses. The functionality of the transmitter is demonstrated for 16 bits and it is compared with different schemes using various design metrics. The proposed ECS transmitter, togetherwith other blocks uses 3830.444nW of power making it suitable for IoT devices.
