نویسندگان
چکیده
This paper presents a technique for programmable switchedcapacitor (SC) filters based on periodical nonuniform individual sampling (PNIS) of each SC structure in the filter. It is shown how very wide range of programmability in all circuit parameters can be obtained, whereas the dynamic range degradation is kept minimum. Experimental results obtained from a 1.2 p m CMOS second-order SC filter are given.

Switched-Capacitor Circuits With Periodical Nonuniform Individual Sampling
The operation of switched-capacitor (SC) circuits with periodical nonuniform individual sampling (PNIS) is introduced. The basic idea consists in a time averaged control of the effective rate of charge delivered by any given SC structure. In this way, the equivalent resistance of each SC branch in a circuit is individually controlled by programming the number of clock pulses in which it is acti...

This work studies the effects of dynamic threshold design techniques on the speed and power of digital circuits. A new dynamic threshold transistor structure has been proposed to improve performances of digital circuits. The proposed switched-capacitor dynamic threshold PMOS (SC-DTPMOS) scheme employs a capacitor along with an NMOS switch in order to effectively reduce the threshold voltage of ...
متن کاملA Sub-µW Tuneable Switched-Capacitor Amplifier-Filter for Neural Recording Using a Class-C Inverter
A two stage sub-µW Inverter-based switched-capacitor amplifier-filter is presented which is capable of amplifying both spikes and local field potentials (LFP) signals. Here we employ a switched capacitor technique for frequency tuning and reducing of 1/f noise of two stages. The reduction of power consumption is very necessary for neural recording devices however, in switched capacitor (SC) cir...
متن کاملComparison of OpAmp Based and Comparator Based Switched Capacitor Filter
Comparator based switched capacitor circuits provide an excellent opportunity to design sampled data systems where the virtual ground condition is detected rather than being continuously forced with negative feedback in Opamp based circuits. This work is an application of this concept to design a 1 order 330 KHz cutoff frequency Lowpass filter operating at 10 MHz sampling frequency in 0.13μm te...
متن کاملCalculating Distortion Levels in Sampled-Data Circuits Using SPICE
This paper presents an analysis technique that can be used to compute the harmonic and intermodulation distortion levels of a sampled-data circuit directly from a SPICE transient analysis. It is useful for analyzing the non-linear behavior of switched-capacitor and switched-current circuits at the transistor level. The approach is valid for all input signal levels, makes no assumption of the un...
