Huddle test measurement of a near Johnson noise limited geophone [PDF]
In this paper, the sensor noise of two geophone configurations (L-22D and L-4C geophones from Sercel with custom built amplifiers) was measured by performing two huddle tests.

Multi-Function Active-Only High-Order Current-Driven Filter
A new multi-function high-order current-driven filter is proposed. The filter uses only operational amplifiers, and operational transconductance amplifiers (OTAs).

Modeling and Simulation of Monolithic Single-Supply Power Operational Amplifiers
In this paper a simple PSpice (Personal Simulation Program with Integrated Circuit Emphasis) macro-model was developed, and verified for monolithic power operational amplifiers operated with a single-supply voltage.

Accurate Settling-Time Modeling and Design Procedures for Two-Stage Miller-Compensated Amplifiers for Switched-Capacitor Circuits [PDF]
We present modeling techniques for accurate estimation of settling errors in switched-capacitor (SC) circuits built with Miller-compensated operational transconductance amplifiers (OTAs).

A simple scheme to implement class AB low-voltage fully differential amplifiers that do not require an output common-mode feedback network (CMFN) is introduced. It has a rail to rail output signal swing and high rejection of common-mode input signals. It

Implicit feed-forward compensated op-amp with split pairs [PDF]
Disclosed are systems implementing an implicit Feed-Forward Compensated (FFC) op-amp, where the main FFC port is realized by the P-side of the CMOS input structure of the 2nd and 3rd stages of the op-amp, while the main signal path is through the N-side.

Generalized mixed-mode S-parameters [PDF]
This paper presents an innovative approach to extend the S-parameter definition to multiport networks having conventional single-ended and differential ports, as is the case for operational amplifiers, transformers and baluns.

Constant-amplitude, frequency- independent phase shifter [PDF]
Electronic circuit using operational amplifiers provides output with constant phase shift amplitude, with respect to sinusoidal input, over wide range of frequencies. New circuit includes field effect transistor, Q, operational amplifiers, A1 and A2, and
