abstract={A simple CMOS-compatible <i>linear </i>voltage controlled oscillator (VCO) has been presented which employs a single CFOA, four MOSFETs and three grounded capacitors as preferred for IC implementation. In the proposed circuit, variable frequency oscillations are obtained by simultaneous variation of two voltage-controlled-resistors in the circuit which appear in the expression for oscillation frequency in the product form but appear as a ratio in the condition of oscillation (which therefore, remains unaffected). The workability of the proposed VCO has been confirmed by SPICE simulations using an exemplary CMOS CFOA and CMOS VCRs both implementable in 0.18¦Ìm CMOS technology.},
