Current-Controlled Current-Mode Quadrature Oscillator Using Translinear Current Conveyors

open access: yesIJITEE (International Journal of Information Technology and Electrical Engineering), 2019
In this paper, a current-mode quadrature oscillator using second-generation current conveyors (CCIIs) is presented. The proposed oscillator consists of two CCIIs, two grounded capacitors and two grounded resistors. The circuit is suitable for integrated circuit implementation by using grounded capacitors.

Cover slip external cavity diode laser

open access: yes, 2007
The design of a 671 nm diode laser with a mode-hop-free tuning range of 40 GHz is described. This long tuning range is achieved by simultaneously ramping the external cavity length with the laser injection current.

Fast control technique for high frequency DC/DC integrated converter based on non-invasive output capacitance current estimation [PDF]

open access: yes, 2010
High switching frequency allows the integration of low power DC/DC converters. Although a high switching frequency would make feasible a voltage mode control with 1MHz bandwidth, parasitic effects and robustness don’t allow such a high bandwidth ...

Electronically tunable current-mode multifunction filter using current-controlled current follower transconductance amplifier

open access: yesInformacije MIDEM - Journal of Microelectronics, Electronic Components and Materials, 2019
A new electronically tunable current-mode multifunction universal filter with three inputs and one output based on current-controlled current follower transconductance amplifier is presented. The proposed filter can realize low-pass, band-pass, high-pass, band-stop and all-pass filtering functions into single topology.
