This product from Analog Devices is Active. Sinusoidal/triangular/square wave outputs. Output frequency up to 25 Mhz. To program the AD5932, the user enters the start frequency, the increment step size, the number of increments to be made, and the time interval that the part outputs each frequency. The frequency scan profile is initiated, started, and executed by toggling the CTRL pin.

MIPS Technologies - Semiconductor design IP

The MIPS SEAD -3 System engineering and development board is designed to provide a low-cost means to support various CPU cores allowing the user to evaluate the cores in an FPGA environment.

SEAD-3 also provides a user the ability to utilize the on board Xilinx FPGA for their own custom programming when a MIPS® FM-3 module is added to house the CPU core. When the FM-3 is added the user can then additionally stack on a MIPS® FPGA 5b board that can house up to two additional Xilinx XC5VLX330s providing extra design capacity.

"With his enterprising spirit, Kibataro Oki (1848-1906) was far ahead of his time in the late 1800s. In January 1881, convinced that the nation was about to enter the age of communications, he founded Meikosha, the origins of today's OKI."

MAX8881 and DS2490 Characterization for Cells

Posted by on Sep 18, 2020 in Battery-Chargers

Rechargeable AA cells are very popular for a large variety of portable applications. The number of brands is also high, and the cell quality can differ considerably. Cell capacity is sometimes different from that specified, and the capacity often deteriorates dramatically after a limited number of discharge cycles. ....

See Maxim Application Note - Simple Characterization Circuit for Rechargeable AA Cells

https://www.maximintegrated.com/en/design/technical-documents/app-notes/3/3874.html

This characterization circuit, plus a PC and some software, accurately measures the full discharge cycle for a rechargeable AA cell. Cell capacity and output resistance can easily be determined from the curve resulting from these measurements.

In Figure 1, the simple circuit is connected to the USB port of a PC. No external power source is required because power is extracted from the USB bus voltage. U1 (DS9490R) is a USB dongle that converts the USB protocol to the 1-Wire® protocol, thereby allowing the PC to communicate with the key circuit component (U2).
