"This book describes the design of low-voltage analog integrated filters using current mirrors, one of the most common building blocks both in analog and mixed-signal VLSI circuits, offering the advantages of low-voltage operation, derivation of resistorless topologies and electronic adjustment capability of their frequency characteristics. Several design examples are described, using current mirrors that fulfill the requirements of modern low-power wireless and biomedical applications, such as universal biquadratic filter topologies, complex filters for Bluetooth/ZigBee low-IF receivers and Wavelet filters for cardiac signal detection. The experimental results from the fabricated chips will also be presented, showing their utility in modern low-voltage low-power portable devices."

"This book presents design methods and considerations for digitally-assisted wideband millimeter-wave transmitters. It addresses comprehensively both RF design and digital implementation simultaneously, in order to design energy- and cost-efficient high-performance transmitters for mm-wave high-speed communications. It covers the complete design flow, from link budget assessment to the transistor-level design of different RF front-end blocks, such as mixers and power amplifiers, presenting different alternatives and discussing the existing trade-offs. The authors also analyze the effect of the imperfections of these blocks in the overall performance, while describing techniques to correct and compensate for them digitally. Well-known techniques are revisited, and some new ones are described, giving examples of their applications and proving them in real integrated circuits. "

"DC-DC boost converter merupakan rangkaian elektronika yang dapat menaikkan (step-up) tegangan DC. Pada proses pengaturan kestabilan tegangan keluaran hasil konversi pada DC-DC boost converter digunakan rangkaian penunjang berupa voltage sensor. Akan tetapi terjadi permasalahan pada bagian voltage sensor yang terganggu karena adanya noise yang disebabkan oleh interferensi switching berfrekuensi tinggi.
Pada skripsi ini akan dirancang dan dibangun rangkaian DC-DC boost converter untuk menaikkan tegangan masukan 48V menjadi tegangan keluaran 200V dengan penambahan rangkaian sensing second orde low pass filter sebagai atenuator noise. Hasil perancangan rangkaian sensing second orde low pass filter dengan perangkat lunak ISIS Proteus menunjukkan respon frekuensi cut off pada 10kHz dengan tipe optimalisasi butterworth low pass filter, sedangkan pada pengujian terjadi pergeseran pada frekuensi cut off menjadi 15kHz.
Hasil perbandingan antara sinyal "A" sebelum dengan sinyal "B" setelah mengalami filter didapatkan sinyal yang lebih baik pada sinyal "B" setelah filter dengan noise yang telah mengalami peredaman.

DC-DC boost converter is an electronics circuit that is used to step-up DC voltage. In the process of regulating the output voltage of DC-DC boost converter, supporting circuit such as a voltage sensor is required to control the stability of the output voltage conversion. However, a problem arises on the voltage sensor component caused by an interference signal generated from a high frequency switching.
In this thesis, we design and develop a DC-DC boost converter to step-up a DC input voltage level of 48V into a DC output voltage level of 200V using a second order sensing active low pass filter as a noise attenuator. The simulation result of the sensing second order low pass filter using the software ISIS Proteus produce a cut off frequency at 10kHz using butterworth low pass filter optimalization, while the actual measurement produce a cut off frequency at 15kHz.
The comparison between sensing "A" signal before and "B" signal after filtering establish a better performance for the "B" signal after filtering with attenuated noise signal.
