Reducing MOSFET 1/f Noise and Power Consumption by "Switched Biasing" [PDF]
, 2000 Switched biasing is proposed as a technique for reducing the 1/f noise in MOSFET's. Conventional techniques, such as chopping or correlated double sampling, reduce the effect of 1/f noise in electronic circuits, whereas the switched biasing technique ...

Double-Sampling Single-Loop EA Modulator Topologies for Broad-band Applications [PDF]
, 2006 This paper presents novel double sampling high-order single loop sigma-delta modulator structures for wide-band applications. To alleviate the quantization noise folding into the inband frequency region, two previously reported techniques are used.

Effects of Non-Idealities of OP-AMPs on Active Filters: An Analytical Study
Active and Passive Electronic Components, 1994 This paper studies the effect of non-idealities of OP AMPs on the performance of active filters. The non-ideality is considered in terms of finite gain, finite gain-bandwidth product, slew-rate, and offset voltages.

Multirate cascaded discrete-time low-pass ΔΣ modulator for GSM/Bluetooth/UMTS [PDF]
, 2010 This paper shows that multirate processing in a cascaded discrete-time ΔΣ modulator allows to reduce the power consumption by up to 35%. Multirate processing is possible in a discrete-time ΔΣ modulator by its adaptibility with the sampling frequency. The

Companding switched capacitor filters [PDF]
ISCAS '98. Proceedings of the 1998 IEEE International Symposium on Circuits and Systems (Cat. No.98CH36187), 2002 In this paper, two possible switched capacitor implementations of companding filters are discussed. The governing difference equations, an estimate of the increase in the dynamic range for a given power consumption and possible topologies are given.
