A Basic Introduction to Filters - Active, Passive and Switched-Capacitor
Filters of some sort are essential to the operation of most electronic circuits. It is therefore in the interest of anyone involved in electronic circuit design to have the ability to develop filter circuits capable of meeting a given set of specifications. Unfortunately, many in the electronics field are uncomfortable with the subject, whether due to a lack of familiarity with it, or a relucta...
متن کاملSwitched-Resistor Filters-A Continuous Time Approach to Monolithic MOS Filter Design
Absfruct-A method of designing continuous-time active RC filters which employ only capacitors and FET transistors is presentedl. The effective RC time constants of these filters are determined by capacitor ratios. The filters employ switched resistors. These filters can uric any existing active RC or passive RC topology as the basis for the design and inherit the sensitivity properties of the c...
متن کاملA Programmable ASIC Design of a Low Sensitivity Sampled Data Filter
In this paper, a CMOS custom Integrated Circuit featuring a multi-stage Universal Switched-Capacitor (SC) Filter is introduced. The network is based on the Generalized Immittance Converter (GIC) configuration, known for its excellent passive and active sensitivities. CMOS switches were used for elements relocation and are digitally controlled to select and realize different filter topologies. S...
متن کاملA Very Low Voltage 9th Order Linear Phase Baseband Switched Capacitor Filter (RESEARCH NOTE)
A very low voltage 9th order linear phase baseband switched capacitor (SC) filter has been designed to be used as part of a cellular GSM (Global System Mobile) receiver. A Gaussian-to-6dB filter of the order of seven is chosen and a second order function is added to reduce the group delay variations around. The filter uses a fully differential topology to increase the dynamic range and reduce t...
متن کاملA Resonant Approach to Interfacing Amplifiers to Switched-Capacitor ADCs Application Note (AN-827)
High sampling rate analog-to-digital converters (ADCs) are commonly used to sample complex modulated signals at intermediate frequencies in modern wireless receiver designs. Often CMOS switched-capacitor based ADCs are selected for such designs due to their attractive low cost and power dissipation. These ADCs utilize an unbuffered front end directly coupled to the sampling network, which prese...
