Abstract	:	A 12-bit 2.8-MHz modulator intended for ADSL applications is presented in this thesis. The design process evolved over two stages, namely, a system-level design stage followed by a circuit-level design stage. During the first phase of the design, the system-level parameters are selected and analog-circuit specifications are derived. The circuit-level stage involved the design of analog circuitry such as operational amplifiers capable of meeting the system-level specifications. The circuit design was carried out in 1-V 65-nm CMOS technology. Double-sampling was employed to make the switched-capacitor circuits more power efficient. Input-signal feedforward was used to lower the signal swing at the output of the opamps. Digital input feedforward is used and presented as an alternative to analog input feedforward.
