Quadrature delta sigma modular design with adjustable bandwidth and center frequency
In this paper, a flexible Continuous time (CT) feedforward (FF) quadrature delta sigma modulator (QDSM) with variable bandwidth (BW) is proposed. The modulator BW and center frequency (fc) are variable which can be adjusted with two separate parameters. The modulator signal-to-noise ratio (SNR) will be optimized by these parameters at every center frequency and bandwidth. The modulator BW is ch...
متن کاملSwitched-rc Radio Frequency N-path Filters
At 14:30 I will give a short introduction to my thesis You are most welcome to attend the introduction, the defense and the reception afterwards. Abstract Tunable on-chip Radio Frequency (RF) filtering is highly desirable for cost effective wireless communication devices. As mobile wireless devices increasingly support multiple RF-bands, tunable RF filtering is wanted. The tremendous growth of ...
متن کاملOn Lowpass and Highpass IIR Filters With an Adjustable Bandwidth
This paper deals with adjustable-bandwidth digital lowpass and highpass IIR filters obtained from a lowpass prototype filter via frequency transformations. Starting with adjustable-bandwidth filter specifications, including requirements on passband and stopband edges as well as on passband and stopband ripples, it is shown how to select the prototype filter and how to perform the frequency tran...
متن کاملPower-complementary Iir Filter Pairs with an Adjustable Crossover Frequency
Complementary infinite-impulse response (IIR) filter pairs can be synthesized to generate power-complementary, allpass complementary, or magnitude-complementary filter pairs (see, e.g., [1]). A very attractive alternative to generate a power-complementary low-pass/high-pass IIR filter pair is to use lattice wave digital (LWD) filters (parallel connections of two all-pass filters) [2]–[4]. Usual...
