    • An apparatus is provided for implementing an enhanced hand shake protocol for microelectronic communication systems. A transmitter and a receiver is coupled together by a transmission link. The transmitter receives an idle input. The idle input is activated when the transmitter is not transmitting data and the transmitter applies a first common 10 mode level to the receiving unit. The idle input is deactivated when the transmitter is ready to transmit data and the transmitter raises the common mode level to the receiving unit. Responsive to the receiver detecting the common mode level up-movement, then the receiver receives the transmitted data signals. After the desired data has been sent, the 15 transmitter terminates communications, drops the common mode level with the idle input being activated.

    • A voltage controlled oscillator circuit and method comprising: a harmonic oscillator having a cross-coupled NFET devices (T1, T2) and an LC tank circuit (L1, L2, C) performing oscillation; a series voltage regulator (210) regulating voltage applied to the harmonic oscillator via a PFET device (T3) and differential amplifier (R); and a tuning circuit (220) having voltage controlled capacitance ‘Zero-Vt’ NFET devices (T4, T5) controlling oscillation of the harmonic oscillator. A differential output buffer (B) provides output buffering to a subsequent stage. This provides advantages that: operation at low supply voltages is facilitated and the sensitive oscillator cell is decoupled from the main supply noise offering improved phase noise performance; the output swing of the oscillator has a well controlled common-mode value which can be selected to most efficiently drive a following stage; and using ‘Zero-Vt’ NFETs facilitates the use of a lower supply voltage.

    • An amplifier control system for regulating the gain of a controlled amplifier. The control system comprises a first signal source for generating a first reference signal. A replica amplifier representative of the controlled amplifier generates an output signal in dependence on the first reference signal. A second signal source generates a second reference signal representative of the product of the first reference signal and a worst case value of the gain of the controlled amplifier. A comparator generates an error signal in dependence on any difference between the second reference signal and the output from the replica amplifier. A negative feedback loop varies the gain of the controlled amplifier and the replica amplifier in dependence on the error signal.
