MHz opamp - RC filter in 0 . 18 p m CMOS
Opamp gain: The main difficulty in building a very high frequency opamp-RC filter is achieving sufficient opamp gain at the filter comer frequency. With the transfer function used here, 34 dB opamp gain results in 1 dB peaking and 30 dB opamp gain results in 2 dB peaking at the comer frequency. (This includes overcoming a 2 dB reduction in loop gain due to capacitance at the opamp input.) A con...
متن کاملA CMOS Frequency Synthesizer Block for MB - OFDM UWB Systems
Chang-Wan Kim et al. 437 A CMOS frequency synthesizer block for multi-band orthogonal frequency division multiplexing ultrawideband systems is proposed. The proposed frequency synthesizer adopts a double-conversion architecture for simplicity and to mitigate spur suppression requirements for out-of-band interferers in 2.4 and 5 GHz bands. Moreover, the frequency synthesizer can consist of the f...
متن کاملMicrostrip Low-pass Filter with Sharp Roll off and Wide Stop-band Using Multiple Cascaded Modified Radial Stubs Resonators
This paper presents a novel microstrip low-pass filter with good performance. A complete detailed theoretical analysis for the proposed filter is given using equivalent circuit models. The proposed filter applying multiple cascaded modified radial stubs resonators provides a sharp cut off frequency response that has a 185 dB/GHz roll off rate. Also, U-shaped attenuators provide a wide stop-band...
متن کاملLow-complexity WLMMSE channel estimator for MB-OFDM UWB systems
Widely linear (WL) minimum mean square error (MMSE) channel estimation scheme have been proposed for multiband orthogonal frequency division multiplexing ultra-wideband (MB-OFDM UWB) systems dealing with non-circular signals. This WLMMSE channel estimation scheme provides significant performance gain, but it presents a high computational complexity compared with the linear one. In this paper, w...
