Pseudo random number generator - element14 Community
Below there is logic circuit of this PRNG: We have here 3 bit shift register which input is feed from XOR gate which is connected to two outputs from this register. It allows to generate number from range 1-7 in according to clock signal. To get here better random sequence you could use generator based on avalanche noise.

Pseudorandom number generator - Wikipedia
February 7, 2026 - They are generally used for generating pseudorandom numbers for large parallel computations, such as over GPU or CPU clusters. They have certain advantages: The only "state" needed is the counter value and the key. For a given counter and key, the output is always the same. This property makes CBRNGs reproducible. Because each random number is computed independently of any previous outputs, they can be generated in parallel.

How to Create a Pseudo-Random Number Generator (PRNG) - Developer Help
This example demonstrates a PRNG using the Configurable Logic Block (CLB) and Serial Peripheral Interface (SPI) peripheral, with the SPI acting as a shift register and the CLB generating the Linear Feedback Shift Register (LFSR) tap feedback and control signals. This hardware-based approach enables continuous, efficient pseudo-random number generation without burdening the CPU.

A variation of the free-running ring oscillator is employed as the pseudo-random number generator, by introducing into the feedback loop of the ring oscillator, an exclusive OR circuit which is connected so that the ring oscillator thereby produces a serial, pseudo-random number sequence.

Pseudo-random sequences are normally generated using a circuit called linear-feedback shift register (LFSR). As illustrated in Figure 14.30(a), it consists simply of a tapped circular shift register with the taps feeding a modulo-2 adder (XOR gate) whose output is fed back to the first flip-flop.

Pseudo-Random Number Generators for Stochastic Computing (SC): Design and Analysis | IEEE Journals & Magazine | IEEE Xplore
In most nanoscale stochastic computing designs, the Stochastic Number Generator (SNG) circuit is complex and occupies a significant area because each copy of a stochastic variable requires its own dedicated (and independent) stochastic number generator. This article introduces a novel approach for pseudo-random number generators (RNGs) to be used in SNGs.

A Hardware Pseudo-Random Number Generator Using Stochastic Computing and Logistic Map
December 30, 2020 - In [12], an algorithm for generating multiple pseudo-random sequences using chaotic functions was developed. The initial values of the chaotic system are calculated and indexed by a based-chaos linear congruences function. All of the above methods are chaos-based PRNGs, and are all realized using software. In addition, many researchers have contributions in hardware implementation of chaos-based PRNGs. In [13], fully digital circuits are used to implement a chaos-based PRNG, and the clock frequency achieves 120 Mhz.

GitHub - amri-tah/Pseudo-Random-Number-Generator-LFSR-Algorithm: Pseudo Random Number Generator using Linear Feedback Shift Register created as a part of the course "Elements of Computing Systems-01" · GitHub
In simple terms, the feedback polynomial is like a set of rules that tell the LFSR how to generate its output sequence. The coefficients of the polynomial represent the taps (or positions) in the shift register that contribute to the next value in the sequence. For example, an 8-bit LFSR, the feedback polynomial is𝑥8+𝑥6+𝑥5+𝑥4+1=0. Hence, outputs of flipflops 8,6,5,4 are summed via XNOR gates and fed back into the first flip-flop. The seed in a Pseudo Random Number Generator (PRNG) implemented using a Linear Feedback Shift Register (LFSR) is the initial state of the LFSR.

The Simplest Of Pseudo Random Number Generators | Hackaday
April 23, 2019 - By contrast it is extremely easy to generate numbers that look random but in fact follow a predictable sequence. A shift register with feedback through an XOR of its output and one of its stages will produce a continuous stream of pseudo-random bits that repeat after a set period.

There are a lot of circuits around advertised as "digital dice". The usual approach is to use a counter which runs at high speed, for a time determined by how long the user presses the button. Since a human can't press a button repeatably for the same number of microseconds, this produces acceptably random numbers.
The purist approach is to use a genuine noise source such as a silicon junction (diodes, especially Zeners), and amplify it. In a suitably shielded case this will produce "real" noise which you can use for cryptographic purposes.

I can not use a mod circuit as it will be deterministic.
the whole algorithm you are using is deterministic - it is a pseudo random number generator. PSNGs are quite useful as they are typically fast and light weight (code size). But they are 100% deterministic.
there are many ways to generate truly random numbers, bot analog or digital. In the digital domain, using adc's lsb is quite popular, as is taking advantage of phase differentials of two oscillators (mostly relaxation oscillators).
