Cell balancing module, voltage balancer device, and method for voltage balancing, particularly for voltage balancing of a stack of batteries
TL;DR: In this paper, the authors proposed a voltage balancing device and method for cell balancing, particularly for voltage balancing of a stack of batteries, which consists of an interface (SPI, VrefH, VRefL) to input a coded reference voltage (Vref) and input nodes (In1,..., InN).

A Digitally Calibrated Bandgap Reference With 0.06% Error for Low-Side Current Sensing Application
TL;DR: A design of an on-chip precision bandgap reference with a digitally calibrated technique is described and Experimental results show that a maximum of 0.06% variation in the bandgap output for a temperature range of −40 °C–100 °C at a power supply voltage of 3.3 V is achieved.
