“…The filter is an important electronic component in modern electronic circuit for information processing [1,2]. However, using traditional electronic devices, such as MOSFETs and resistors to implement integrated tunable filter will consume a lot of circuit area with a large number of devices and cause high energy consumption [3,4]. Emerging as a new electronic device, resistive random access memory (RRAM) has been intensively studied in the past decade due to its simple structure, compatibility with CMOS process, high storage density, fast reading/ writing speed and low power consumption [5][6][7].…”

In this work, the multilevel resistive random access memories (RRAMs) have been achieved by using the structure of Pt/MoO 3 /Hf/MoO 3 /Pt with four stable resistance states. The devices show good retention property of each state (>10 4 s) and large memory window (>10 4 ). The simulation and experimental study reveal that the resistive switching mechanism is ascribed to combination of the conductive filament in the stack of MoO 3 /Hf next to the top electrode and redox reaction at the interface of Hf/MoO 3 next to bottom electrode. The fitting results of current-voltage characteristics under low sweep voltage indicate that the conduction of HRSs is dominated by the Poole-Frenkel emission and that of LRS is governed by the Ohmic conduction. Based on the RRAM, the tunable high-pass filter (HPF) with configurable filtering characteristics has been realized. The gainfrequency characteristics of the programmable HPF show that the filter has high resolution and wide programming range, demonstrating the viability of the multilevel RRAMs for future spiking neural network and shrinking the programmable filters with low power consumption.

“…In contrast with passive polyphase filters, active polyphase filters have the general advantages of small chip area, high signal gain and easy tuning. Many active polyphase filters have also been discussed in some literature [19,20,21,22,23,24,25,26,27,28,29,30], but few of them achieve strong image rejection at high operating frequency and low-power dissipation.…”

In this letter, a new circuit structure for CMOS active polyphase filter is proposed and analyzed. In the proposed structure, the currents produced from two cascode stage with a capacitor and single cascode stage in a single-stage are used to realize high-pass and low-pass functions, respectively. Compared to other conventional active polyphase filters, the proposed polyphase filter uses a simpler structure to achieve strong image rejection at the higher frequency while obtaining lower power consumption and smaller chip area. In the 0.18-µm CMOS process, the proposed active polyphase filter occupies less than 0.36mm 2 of chip area. From the measurements, the four-stage active polyphase filter shows an image rejection ratio of more than 58.2dB at frequencies of 26MHz to 65MHz, a voltage gain of 5.8dB and an IIP3 of 1.5dBm at 45 MHz while consuming only 2.64mA from a 1.8-V supply.
