highlighting the path towards more efficient and scalable modulation solutions in future integrated circuits. Delta-Sigma Modulation: A method of analogue-to-digital conversion that employs ...
Speaking about modulation, in simple terms, it's the method used to impose the message signal on a carrier signal, which is then transmitted by antenna or wire. And demodulation is ... In the above ...
The inherent features of the delta modulation also provide control of ratio of voltage to frequency and commutation numbers of an inverter without much complexity in control circuit. These and other ...
Abstract: A fourth-order discrete-time delta-sigma modulator (DSM) was fabricated using a 65-nm CMOS technology. It combines low-complexity circuits and digital calibrations to achieve high speed and ...
Unfortunately, the input stimulus remains unidentified for the majority of these circuits. Therefore, development of a synthetic method for stimulus-independent modulation of these circuits is highly ...
3.2 OFDM modulation and demodulation An OFDM symbol is a mixed-signal of multiple modulated subcarriers, which could be modulated by PSK and QAM. The OFDM transmitter transforms the bit-stream ...
