Low power transmitter for remote control

摘要

A transmitter for remote control includes a first analog-to-digital converter (ADC) to receive a first audio signal from a electronic device and convert the first audio signal to a first direct-current (DC) signal, a first boost circuit connected to the first ADC to receive and amplify the first DC signal, a second ADC receives a second audio signal from the electronic device and converts the second audio signal to a second DC signal, a second boost circuit connected to the second ADC to receive and amplify the second DC signal, an energy storage element and a transmission module is powered by the energy storage element and generates a carrier signal, the transmission module receives the amplified first DC signal from the first boost circuit, the amplified first DC signal modulates the carrier signal generated by the transmission module, and the amplified second DC signal charges the energy storage element.
