A Ringamp-Based DAC for Compute-in-Memory
A ring amplifier based switched-capacitor digital-toanalog converter (DAC) for charge-domain compute-in-memory (CIM) arrays is presented in a $65-\mathrm{nm}$ CMOS process. The proposed architecture employs a dual coarse/fine output stage with Monticelli and diode biasing, enabling fast slewing and stable operation acr...
