Dual-Stage Feedback Techniques for Single-Pole Feedback Compensation Download White Paper 297Ko

This technical paper proposes and studies the effects of a dual-stage compensation technique for achieving greater than 100kHz crossover frequency of a single pole system converting from 48 V to 1.2V.  By placing a separate non-inverting gain stage after the error amplifier, the necessary gain-bandwidth of the op amp can be significantly reduced allowing for high crossover frequency and good transient response.

This month, Oscium is giving away three of its iMSO-204L dual analogue iOS oscilloscopes, worth USD400 each. Designed with native Lightning compatibility, the iMSO-204L transforms the iPad, iPhone, and iPod touch into an ultra-portable, two-channel oscilloscope.

Since Apple changed its connector, Oscium has been working to bring native compatibility to its customers. The third generation of handheld engineering tools from Oscium, the iMSO-204L is the solution to the connector change, featuring two analogue and four digital channels, capable of 50 MSPS at a 5MHz bandwidth, and with a resolution varying from 200ns/div to 10s/div.
