- Single amplifier bi-quadratic filter topologies in transimpedance configuration
[作者:Chandra, Gaurav (1); Tadeparthy, Preetam (2); Easwaran, Prakash (3) ,期刊:IEEE Transactions on Circuits and Systems II, 页码:502-506 , 文章类型: article (JA),,卷期:2008年55-6]
- Abstract:Active-RC configurations, implemented as cascaded bi-quadratic sections (biquads), are the filters of choice for low distortion applications in the base-band. For low power and area applications, single amplifie...
- A tunable pseudo-differential OTA with - 78 dB THD consuming 1.25 mW
[作者:Luján-Martínez, Clara (1); Carvajal, Ramon Gonzalez (1); Galán, J. (2); Torralba, A. (1); Ramírez-Angulo, J. (3); López-Martin, Antonio (4) ,期刊:IEEE Transactions on Circuits and Systems II, 页码:527-531 , 文章类型: article (JA),,卷期:2008年55-6]
- Abstract:A novel linear tunable transconductor based on a combination of linearization techniques is presented. The input signal is transferred to the V-I conversion element by means of a high-speed feedback loop. Then, ...
- Radix-3 × 3 algorithm for the 2-D discrete Hartley transform
[作者:Wu, J.S. (1); Shu, H.Z. (1); Senhadji, L. (3); Luo, L.M. (1) ,期刊:IEEE Transactions on Circuits and Systems II, 页码:566-570 , 文章类型: article (JA),,卷期:2008年55-6]
- Abstract:In this correspondence, we propose a vector-radix algorithm for the fast computation of a 2-D discrete Hartley transform (DHT). For data sequences whose length is a power of three, a radix-3 × 3 decimation...
- A calibration technique for very low current and compact tunable neuromorphic cells: Application to 5-bit 20-nA DACs
[作者:Leñero-Bardallo, Juan A. (1); Serrano-Gotarredona, Teresa (1); Linares-Barranco, Bernabé (1) ,期刊:IEEE Transactions on Circuits and Systems II, 页码:522-526 , 文章类型: article (JA),,卷期:2008年55-6]
- Abstract:Low current applications, like neuromorphic circuits, where operating currents can be as low as a few nanoamperes or less, suffer from huge transistor mismatches, resulting in around or less than 1-bit precision...
