This work presents a general method to design continuous-time Σ∆ modulators with sine-shaped feedback DACs. A discrete time to continuous time transformation technique is used to compute the continuous-time loop filter coefficients, taking into account the sinusoidal feedback. Examples of high order lowpass and bandpass continuous-time Σ∆ modulators are(More)
The fast development of wireless communication systems requires more flexible and cost effective radio architectures. A long term goal is the software defined radio, where communication standards are chosen by reconfiguration of hardware. Direct analog to digital conversion of the radio frequency (RF) signal is still unrealistic at present time, due to the(More)
