“…2(a) exhibits desirable input impedance characteristics, when used as a TIA with low input resistance as shown in Fig. 2(c) and in [17] or as a differential TIA in [18], this circuit is expected to have an unsatisfactory stability behavior when large gain is desired. To illustrate this, consider that when a lossless resonant network is formed by the input active inductance, , and the photodiode capacitance.…”

“…In other words, the input resistance can be made zero if the input complex-conjugate pole-pair frequency, which is associated with and the capacitance at the input, is much larger than the desired bandwidth. However, despite having lower transimpedance gain than the RGC TIA, this circuit can be utilized as a TIA that is insensitive to large photodiode capacitance and can tolerate large variations of total capacitance at the input since [18]. To avoid the stability problems but still to utilize the low input resistance and the active properties discussed above, the MIC can be combined with the RGC TIA to form the MIC TIA shown in Fig.…”

This paper presents an inductorless 0.13-CMOS TIA structure that is a modified version of a regulated cascode (RGC) TIA. An immittance converter is incorporated to reduce power consumption while increasing transimpedance gain. Measured 3-dB bandwidth is 7 GHz, sufficient for 10-Gb/s operation, in the presence of 250 fF capacitance at the TIA input, representative of typical CMOS photodiode capacitance. The transimpedance gain of the single-stage TIA is 50 , and the group-delay variation is less than 19 ps over the 3-dB bandwidth. The circuit occupies an active area of and consumes 7 mW from a 1.5-V supply. The measured average input-referred current noise of the TIA is 31. Simulations and analysis show that the proposed single-stage TIA architecture is capable of achieving improvement in the transimpedance limit over a single-stage RGC TIA designed for the same data rate and the same input photodiode capacitance. A comparison of measurement results to published TIAs also demonstrates the competitive performance of the proposed TIA in terms of the TIA transimpendance gain, bandwidth, area, and power consumption. in 2011.

This letter presents a low-power transimpedance amplifier (TIA) that employs an immittance converter, which provides both a negative input resistance to increase the input pole frequency and a negative inductance to improve the circuit stability. These allow for a significant bandwidth enhancement with low power consumption. Two TIAs, TIA1 with 6 GHz and TIA2 with 8.8 GHz 3 dB bandwidths, were fabricated in a standard 0.13-CMOS technology and were designed to operate with a 250 fF photodiode capacitance at 10 Gb/s. The transimpedance gains of the single-stage TIAs, followed by near-unity-gain output-matching buffers, are , the group-delay variations and average input-referred noise currents are and (TIA1) and and (TIA2) over their 3 dB bandwidths. The TIAs occupy an active area of 250 160 , and without the output-matching buffer each consumes 2 mW.Index Terms-CMOS optical receiver, cross-coupled pair, immittance-converter, transimpedance amplifier (TIA).

In this paper, a modified Regulated Cascode (RGC)-based, low-power, transimpedance amplifier (TIA) is proposed followed by a closed-loop gain stage beside an added level shifter circuit to the booster of a conventional RGC circuit to set the proper biasing conditions for the transistors in the proposed TIA structure in 90-nm CMOS technology. Moreover, the added gain stage benefits from an active inductor which resonates with the output capacitance of the TIA circuit to extend the bandwidth while saves the occupied chip area in comparison with passive inductor schemes. In addition, the performance of the proposed TIA circuit is simulated in HSPICE using 90-nm CMOS technology parameters which show a transimpedance gain of 41 dBΩ, −3-dB frequency bandwidth of 3.7 GHz, input referred noise value of 834nA rms , and the power consumption value of only 1.4 mW at 1-V supply.
