It employs a direct input transfer architecture using a single coupling capacitor (CC) and introduces a static current-free pre-sensing technique to minimize offset voltage (VOS), area, and energy overhead. Unlike conventional offset cancellation (OC)-based I/O sense amplifiers, which suffer from input voltage attenuation, large area due to dual CCs, and static current during sensing, SCFP-IOSA eliminates attenuation by directly transferring the input differential voltage (ΔVGIO) and avoids static current using exponential RC pre-amplification. The proposed design separates ΔVGIO generation and sensing by GIO switches, allowing simultaneous offset cancellation and input development. This reduces sensing time overhead and enables a fast sensing time of 3.75 ns, with 2.15 μW power consumption, and 10.28 μm² area, achieving 3× lower σVOS, 2.9× lower power, and 4.46× smaller area compared to state-of-the-art OC-IOSA. Moreover, it shows robust sensing yield even in noisy conditions, and maintains performance at low supply voltages. These characteristics make SCFP-IOSA highly suitable for next-generation low-voltage, high-density DRAM applications, particularly in 1Ynm-class or beyond. 2025-07-04 BL Sense Amplifier • The proposed sense amplifier, named the Dual-Input Stacked Inverter-Based Single-Ended DRAM Sense Amplifier (DISA), is a monolithic, low-power, high-speed sensing solution for DRAMs fabricated in 28 nm CMOS technology. It employs a dual-input stacked inverter architecture with bit-line (BL) switches and a single-ended structure to minimize area, power, and timing overhead. Unlike conventional bit-line sense amplifiers (BLSAs) that rely on differential coupling capacitors and require a dedicated offset-cancellation (OC) phase, DISA performs offset cancellation and charge sharing simultaneously. This eliminates the timing penalty from OC time and enables the fastest sensing operation, achieving sensing times of less than 9 ns at 0.7 V and less than 8 ns at 0.8 V, defined as the time when BL and BLB reach 80% and 20% of VDD, respectively. Thanks to its single-ended topology and use of only one coupling capacitor, DISA occupies the smallest area among compared designs and supports high-density DRAM layouts with sub-50 nm bit-line pitch. The dual-input stacked inverter enhances gain by using stacked transistors operating in the linear region, significantly reducing static current in both the OC and main sensing phases. In addition, direct BL connection to the IN node improves noise immunity by avoiding floating nodes and ensuring robust sensing even under process scaling and voltage reduction. Overall, DISA demonstrates superior energy efficiency, achieving the lowest measured sensing energy of 5.8 fJ/cycle/bit, and supports low-voltage operation down to 0.55 V, making it highly suitable for advanced low-power DRAM applications. 2025-07-04 Unity-gain buffer The "Unity-Gain Buffer" is a low-power, fully differential analog buffer IP designed for high-speed, low-distortion applications requiring voltage following with minimal offset and excellent linearity. The IP is composed of a differential-input, single-ended-output operational amplifier configured in a unity-gain feedback topology.
