2022年9月15日 · XOR Gate Example Circuit: Toggle Flip flop You can use the XOR for lots of things. Below is an example circuit with an XOR gate, and a D flip-flop to create a T flip-flop .

2011年10月17日 · Since FF1 just flips on alternate clocks, you can connect its Q' (inverted) output directly to its D input to achieve that. FF2 goes high after FF1 goes high and stays high until both FFs are high. Thus you can connect the Q output of FF1 to one input of an XOR gate, and the Q output of FF2 to the other XOR gate input.

2024年5月15日 · The flip-flop is a circuit that maintains a state until directed by input to change the state. A basic flip-flop can be constructed using four-NAND or four-NOR gates. Flip-flop is popularly known as the basic digital memory circuit. It …

In this paper, a novel flip-flop using clock gating circuitry with embedded XOR, GEMFF, is proposed. The new flip-flop uses clock gating to reduce redundant clock switching power. In view of power consumption, GEMFF outperforms CSFF by 25.1% at switching activity of 10%.

2023年6月19日 · This paper presents a pseudo-random binary sequence (PRBS) generator using merged XOR-D flip-flop as building blocks. The proposed architecture uses differential cascode voltage switch logic (DCVSL)-based dynamic XOR gate.

2016年6月17日 · Implementing XOR is simple, and can be accomplished by using 8 transistors plus inverters. NOR gate would need 4 additional transistors. So, using just 12 extra transistors on top of the existing flip-flop circuit, you get a self-gated flip-flop with minimal dynamic power! How's that for a circuit?!

In this thesis, I have designed different circuits of D-flip flop based on XOR/XNOR gate using CMOS inverters, NMOS digital switches, pass transistors and GDI cell. Each circuit structure has been designed using 32nm UMC CMOS technology.

We typically build finite state machines from combinational logic (next state logic) and latches or flip-flops (storage elements) to store the state information. We then control latches and flip-flops with a clock to create synchronous logic circuits.

Different designs of XOR/XNOR gate has been designed using different components like Transmission Gates, NMOS switches, Pass Transistors & GDI (Gate Diffusion Input) cell that can be operated at higher frequencies. All designs have been designed using 32nm UMC CMOS technology and compared for the supply voltage range from 0.9V to 1.5V.

2013年6月8日 · Dual-edge triggered flip-flop is a sequential element which samples data at both positive as well as negative edges of the clock. This might come in handy in applications where the throughput is very high.
