This letter reports a broadband low-noise amplifier (LNA) with input-referred noise reduction and coupled-inductive-peaking technique in CMOS technology. First, combination of resistive-feedback inductive-degeneration is proposed to mitigate the noise. The high-frequency currents generated by feedback resistor input transistors are partially suppressed gate inductor. Second, LNA utilizes two-stage achieve high flat <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML"...

This paper presents two high-efficiency charge pumps (CPs) by utilizing the gate voltage boosting technique (GVBT). Unlike traditional bulk-CMOS and all-NMOS CPs, an input bias is independently applied to terminal, it improves current driving capability without need of large pumping capacitors or high-frequency clocks. Meanwhile, GVBT decouples state transistors from clocks connected capacitor, can eliminate reversion loss in both main auxiliary circuits. Fabricated a 0.18- <inline-formula...

In this paper, a single-stage Super Class-AB operational transconductance amplifier (OTA) using current reuse technique is presented. It based on two scaled mirrors located at the tail nodes of input pairs, reusing through cross-coupled pairs by gain factor α, and delivering new currents to output branch, enhancing overall (Gm) (1+α).
